  • HarleyHolland7 Harley Holland (@HarleyHolland7) reported

    @O2 I need to change ownership of an account in order to keep the same number when I change sim. I’ve called customer service and they told me to make an account, how can I do this when the number I use is linked to the account I need to change ownership for ? Useless.

    @O2 Am a new O2 customer in the CB3 0 postcode area. Enabled my SIM today to find almost no signal on 2G and 3G, can't connect to 4G. Can you give me more details on the local network outage and when it might be fixed? If not, caution demands I stay with my existing provider.

    @o2 have taken £495 of my money and sent me a bag with a leaflet in. I have sent video evidence of me opening the delivery which they claim was my full delivery. As I don't have a phone with them the only way I can contact is twitter. Worst service I have ever received. Appalling

  • modtl11 Steven Tattum #KeepWalesSafe 💙 (@modtl11) reported from Connah's Quay, Wales

    @O2 hi. I have messaged many times about transferring my dad's payg number to his new contract. The page on the app is STILL offline, the o2 shop couldn't do it and 202 just tells us to use the app which doesn't work. I'm getting rather angry now about this.
