Utterly appalling and useless customer service. I tried to upgrade to a new contract on their phone app but all of the upgrades were coming in at £50+ per month. I looked online and found a contract with them on a comparison website (there were no contracts like this on their upgrades part of the website/app). I used their webchat service to ask what I needed to do next because I was still paying monthly but outside of my contract. I explained all of the above to the idiot on the webchat. It took them an entire hour to finally help me but not before they tried to upgrade me to a £50.94 per month, 36 month contract. When I told them to go and multiply they came back at me with a £29.94 per month contract for 36 months. Decided to complain but judging by online reviews, this will be a waste of time. Avoid these utter idiots.
