Truly awful customer service. Apathetic and incompetent when they bother to respond. Don't do what they say they'll do, go back on it anyway.

HQ - I struggled, but go to Redhill, Surrey - they have extremely helpful and knowledgeable staff, that give you the time to resolve your problem - if they cant, then no one can ....................

I rang and asked for PAC code well after ten phone calls and text messages I still haven’t received any e mails to confirm my move. I couldn’t understand the person I was speaking to he just kept on calling me and asking the same questions about my name, postcard, e mail address and bank details of which I told him time after time. Then finally he asked me for my bank details again for a charge of £1 to finalise I think it was to cancel my a/c. I was tied up in knots and got very stressed I had to keep confirming all the details ever time he called. Now I am not sure if I will be able to transfer to my new provider now being Monday. I know this might be a coincidence but I have had an amount appear on my current a/c which is pending awaiting for the full amount. I have no idea what shop this is referring to so have had to put a stop on my card. You never know these days of scamming. Hate having to do everything on line. Very stressed!!!

They don’t care about customers they just send bills and when you try to raise a complaint they don’t even care or respond

I would give a minis score if I l could - Appalling customer service. I have a 30gb plus ( switch up contact) but hey deactivated the switch up option without Informing me. They said they don't know why it has happend but will not do anything until it is investigated. I wanted to upgrade and receive the upgrade offer. (Free earbuds etc) Bit looks like I will miss the timescales. After being and waiting on the phone for 2 hours whilst the customer services women was trying to contact a colleague they eventually told me they would ring me back - that was 2 days ago and I'm still waiting - absolutely shocking treatment to a long standing customer. O2 NEED TO GET YOUR ACT TOGETHER AS YOU WILL LOSE MANY MORE CUSTOMERS.

I have never experienced such appalling treatment from any company as I have with O2. I have been with them for years. Since 28th July 2025, when my service (and my wife’s) stopped working after following O2’s own migration process, my life has been turned upside down. I followed this process of advice received in store and on the call with multiple agents. For a month now I have been left with no working phone service – unable to reliably make or receive calls or texts. I had to purchase a EU virtual sim abroad just to reach family. This has caused huge distress and disruption to both my personal life and business. Clients can’t reach me, I can’t receive important messages, and I have been left completely stranded while abroad. During this period, O2 has: 1. Lied to me multiple times — promising follow-ups and resolutions that never came. 2. Hung up on me during calls when I pressed for answers. 3. Sent me boilerplate, copy-paste emails that ignored all the details I had provided. 4. Wrongly closed a complaint claiming they had spoken to me and resolved the issue — a complete fabrication. 5. Opened multiple complaint numbers instead of fixing the problem: • C-2908257167 • C-3107256997 • C-0508257082 6. Sent me a bill for £54, which I disputed and then paid under protest just to protect my credit record. Despite this, O2 still escalated me to a debt collection agency, causing further stress and humiliation. The emotional toll this has taken is severe. I have lost time, money, and peace of mind. I have spent hours chasing O2, repeating myself, and getting nowhere. Instead of helping, they have added to the distress with threats of passing me to debt agency (even though I paid and informed them in advance that I am happy to pay, but couldn’t as I have also been logged out of MyO2 App). This is not just poor service — it is negligence. O2 has failed at every level: technical, customer service, billing, and complaints handling. The complains handling is HORRENDOUS! They have shown no accountability and no care for the impact on their customers. If you are considering O2, think twice. They have left me without service for weeks, damaged my mental health, and harmed my business. I wouldn’t wish this experience on anyone I am completely lost in how to receive any help. I told them multiple times I cannot receive calls on my O2 number as it’s no longer working and their boilerplate replies insist they will email me and call me. Nothing!

Very disappointed with the service I've been given considering I've been a loyal customer for over 10 years with numerous devices on my contract. And as such when contract runs out I will definitely be considering going with another service provider.

A bad experiences putting it very mildly O2 must be the worst mobile network in the UK no customer service no help at the shop and a complete waste of time as the app doesn't work properly keep sending you to Virgin media also what they don't understand is the difference between a mobile phone and a dongle perhaps they should go back to school and learn the difference customer service does not exist if it does please let me know absolutely atrocious network

What went wrong you ask? I think the correct question is what didn’t go wrong. I have been a customer of o2 for several years, and they successfully disappoint every single time. My worst experiences have always been with o2’s customer service. My dog could have solved my issues compared to the jobworths over the phone. I informed o2 I was moving abroad on several occasions, but apparently there is extreme difficulty in understanding that. 02 definitely teaches you that common sense is not so common and that bare minimum intelligence is not a flower which grows in every garden. A certain individual over the phone informed me the “only way” to cancel my UK phone number was to return to the UK and visit a UK store. As you can imagine, I thought it was sarcasm. After many phone calls I eventually managed to cancel my UK number and I am now with a different provider who actually has employees which have common sense.

Don’t join O2. Been with them +20 years. Used to be good and the shop staff still are. But their online function is useless and calling them will make you so frustrated. Hours and hours of my life on hold listening to awful music to then talk to someone who does not speak English properly nor know anything and then get cut off.

Think they are bigger than the UK government and won't listen to anything you say, unless they are taking money from you than it's the easiest thing for them to process. Any complaints or anything else, they struggle to deal with. Honestly pick a better phone provider. O2 really do not care about you as a customer.

Check in staff were friendly & really helpful. Everything was clearly explained & easy to follow. Tom our guide was so well spoken, clear with his instructions & was genuinely a really nice man. He engaged with all people in the group & was informative when explaining the sites from our resting point at the top. Would definitely recommend!

I have been with 02 for 25 years. My income came in late and after I paid my bill on 04/07/25 instead of 30/06/25, the O2 declined to reinstate the service. On the day I paid the bill, O2 wrote me a note claiming that my out-off-allowance spend is barred and will not be able to spend outside of my current allowance until the bill is paid whereby the bill had already been cleared.

Terrible unhelpful customer service. Total waste of my time of 30 minutes ! ! Asked two simple questions only. 1. How much data for EU left out of 25G? (not the general total data amount which I can easily see in my online account) 2. Why is the extra charge shown in my O2 online account which will be deducted from my bank next week? Simply answered to accept extra money taken out from my bank account first and then try to contact them at that time again to ask why ! ! And they can’t see EU data allowance left in my account. I need to know before I go EU again !
