    @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 hi, I am trying to use the £20 voucher off virgin experience days with priority, however, it will not allow me to use the code as it says I have already used it - which I haven’t used at all. @VirginExp Can you please 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!!
