    @O2 trying to sign in on the app but it says my account is not activated. Can you please resend me my validation email?

  • naveenakb2 naveenakb (@naveenakb2) reported

    @O2 I am still waiting, I was told someone will call me and I haven’t heard anything from the fraud team. I have called customer service 3/4 times and all they have said is to wait for the team to get back to me but it’s way over the SLA given and stuck with a fraudsters bill

  • Deanerobinson Deane Robinson (@Deanerobinson) reported

    @O2 Disney plus extra for £5.99 per month still not working. Constantly get error message saying oops there’s been a problem

  • iamhafiz91 Mohammed Hafiz (@iamhafiz91) reported

    @O2 can not believe how bad your data/network is. Can’t connect to the internet when outside. Whats the point in having 120gb when I’m only able to use like 5gb in a month. Get it fixed

  • Andy_TheGrouch Andy (@Andy_TheGrouch) reported

    Really starting to hate @o2, phone is practically unusable with data / signal dropping out all the time.

  • thatssosky scattered particles (@thatssosky) reported

    @O2 Hi, the voucher for tomorrow odeon is saying it’s invalid. Can someone help please

  • adg273 Adrian (@adg273) reported

    @O2 The apple website says if my son doesn't have his own iphone, I can setup his watch on my phone as a standalone device and we don't need to be on the same carrier network though?

  • jamesmrobinson James Robinson (@jamesmrobinson) reported

    Anyone else find they often have 4/5 bars of 5G but absolutely no service? This is on @SkyUK Mobile (@O2 network) in several locations. Might just switch it off and go back to the slower but reliable 4G!

  • JusticeBenson JUSTICE 🇳🇬🇬🇧 (@JusticeBenson) reported

    @O2 I'm still waiting for a call back. This is why I am shocked at how @O2 treat customers that pay their bills IN ADVANCE. 😑
