    @O2 Help! I’ve got a sim only contract with you and tried to change tariff for more mins but selected the wrong one. I clicked on ‘cancel tariff change’ and got a message to say the cancellation had been requested. How long do I need to wait before I can make the change? Thanks!

    Hi @O2 I've been having problems with my 4G for the last couple of weeks. Not really happy with this considering the amount I pay each month and how long I've been a customer. When can I expect this issue to be sorted?

  • s55143346 s (@s55143346) reported

    @O2 don’t ever get a contract with O2, the amount of times I have complained about 5G internet and no one has dealt with my complaint is ridiculous! Never ever would get a contract with O2 again! Worst phone company ever. My girlfriend is with EE and she always praises them!

    @O2 thanks for cutting me off all weekend. Also, unable to resolve issues despite phone calls, web chats and letters. How do they get away with it?

  • HC1998 HC (@HC1998) reported

    @O2 @Apple @O2 no point in getting anything on O2. Rubbish signal. Rubbish CustomerService

  • CryptoBen_10 C₿ (@CryptoBen_10) reported

    @O2 why can I literally not get 4G signal anywhere I go now? I live in a major city centre and I can’t remember the last time I had 4G signal. The signal I’m getting is absolutely shocking. Needs sorting ASAP or else I’m going to another network provider

  • Tonie_Mi Tonie-Mi (@Tonie_Mi) reported

    1 week and still no replacement phone nor any alternatives are in stock. Only solution offered is to wait until one happens to come into stock. The amount they charge in premium and this is the sort of service you get. Poor. Do better @O2 #O2insure

  • MancVintage73 Tracy Field (@MancVintage73) reported

    @O2 trying to get through to pay off device plan and cancel airtime on a dongle but having a complete nightmare getting through. 45 min wait but the automated system to get your call through is an absolute joke and can’t point me in the right direction!!

  • LeeShields1101 Lee Shields (@LeeShields1101) reported

    @O2 Hi there, I was wondering if you could help? I'm trying to get a SIM only deal for my Mum, but she needs to keep the same phone number. Can you help me with this? I have learning disabilities, so this is pretty confusing and stressful for me
