Unacceptable Customer "Service". I've had a week of their crap customer service regarding a problem with my account whilst trying to upgrade to a new phone and tariff. I called Monday 16th January to upgrade. It was all agreed that I was upgrading to an iPhone 7 Plus 128GB handset on a 24GB per month (half price for first 6 months) tariff. This was all agreed, T's & C's were read to me, the new contract was agreed on the phone and I was told I'd receive the phone on Wednesday 18th January. Brilliant! However. I then got a phone call from Vodafone about 40 minutes later saying that there was a problem with the upgrade and was told that I couldn't upgrade as this month's bill hadn't been paid yet, so I asked to be transferred to billing and paid it in full straight away. Then, I was transferred back to the upgrade department and I was connected to a different person who told me that my account was showing a "promise to pay" on it and they couldn't do anything for me! I had JUST paid my bill and hadn't asked to have a promise to pay set up. The guy on the phone also told me that I couldn't have the tariff I'd been told I could and agreed to, as they don't offer the half price on the 24GB data tariff. He also told me that the iPhone 7 Plus wasn't in stock and I'd have to wait 1-2 weeks minimum for it but he couldn't do any upgrade for me due to this thing on my account. I asked to speak to a manager, but was told they don't speak to customers on the phones (how professional). I then spoke to a senior member of staff who told me they were going to sort the problem and get the upgrade done for me "on the spot". They struggled to get this promise to pay taken off my account, and it is STILL on there FIVE DAYS LATER, and I am still unable to upgrade. I have made about 7 phone calls to Vodafone and logged 2 formal complaints. Neither of which have been dealt with. One of the people I dealt with regarding the first complaint told me she would call me back the following day at 12pm to update me with the progress but never did. The second person cut me off whilst I was on hold and never rang me back. They supposedly escalated the problem on Tuesday regarding getting this stupid promise to pay off my account and I was told that it would take 2-3 DAYS to do and I would get a call back once it was done. It is still on there and I haven't had a single call back as promised. I finally spoke to someone on Wednesday as I decided to call and try again to resolve it and I was told that it was fine, they've been able to work around the problem and my phone would be on its way to me for Friday delivery as I'd missed the next day cut off. Great! Finally all sorted! NO!!! I checked my DPD account this morning to make sure it was all going to plan, and it was showing as no deliveries scheduled. So I called a Vodafone AGAIN and I was told that my order had been automatically cancelled as the account was showing as being in "Collections". I demanded to speak to a manager. Again, told they weren't able to get a manager on the phone and instead put me through to a senior advisor. I was told that I had been lied to by the previous service advisors with respect to being upgraded and with regards to the phone I asked for being sent. I'd also been told false information regarding the phone's availability and that they have no stock of the 7 Plus whatsoever and that depending on colour choice, it would be a 1-2 or a 2-4 week wait. By this point I was seeing red. I have been told lie upon lie by numerous different staff over the last 5 days. I have been transferred to departments that weren't anything to do with the situation. I have been cut off by the advisor whilst being on hold. I have entered TWO separate agreements and had both cancelled. I had been told by a senior advisor that Vodafone HAVE to keep to any promises they've made their customers and I've had nothing close to that. And, to top it off, despite this situation being escalated TWICE to get something I didn't ask for on my account removed, it's still on there and I am still unable to upgrade. I have been told it's been escalated to the highest standard and it will be sorted but not given any time frame. Apparently once they've had a delivery of phones, they'll call me to tell me. But I've been promised a call back 3 times and only had 1 return my call. That was by Gemma today who was rather helpful. I am appalled by the service overall though. I've spent thousands of pounds with Vodafone the last few years and I'm trying to upgrade to an even higher tariff than I'm already on and spend more money, and this is the service I get! I wouldn't have minded so much if I had been told the truth from the start, but I wasn't. The service at this company is the worst of ANY UK network and I wouldn't recommend Vodafone to anyone whatsoever. Appalling company and total sham when it comes to customer service. No doubt this will have been a futile type up too as I can't imagine anyone will even bother replying or helping to resolve this issue and compensate for the trouble of the last week. I would have rated less than 1 star if the option was there.
