    @O2 Hi o2, I'd like to talk about upgrading my phone early. I have £80.53 remaining to pay on my 36 month contract but the upgrade offers for the iPhone 13 are far too extortionate compared to what I pay now. I notice other providers offer more competitive deals. Can you help?

    @O2 When are you going to address my issues - the fraud taking place on my account that you allow and are continuing to allow while charging me even though I have reported this to you since Saturday. So annoyed!!

    @O2 hello, when will you be resolving the issue with no SMS and no data in Newbury town centre? It's been down for quite a few days now. Works fine elsewhere, restarted phone etc. Thanks

    @O2 the network in Southwark (London) has been awful for days. Any chance of this getting sorted before the end of the year?
