  • danboy Danny Hatchard (@danboy) reported

    @O2 why is your signal so bad everywhere I go? And why is 4G always faster than 5G? I moved over to O2 after being with EE for years. What a mistake

  • RyanF_88 Ryan Foulkes (@RyanF_88) reported

    @O2 Terrible customer service

  • AmendMe Me (@AmendMe) reported

    @O2 we’re abroad at present. A friend is an o2 business account holder however she’s concerned about roaming charges. She’s accessed her account but there’s no info on it to suggest what has been used, charges etc. can you help?

  • adamsn Nj (@adamsn) reported

    @O2 I spent half an hour waiting to speak your customer service team. Then got out back on hold for another 30 mins to be put back through to payment management team only to put back to customer service. It took me a hour and 15 to resolve the issue.

    @virginmedia @TheBHF @O2 Service outages in 3 of last 4 days and now putting up monthly bill by 22%

  • RogerSmith0909 Roger Smith (@RogerSmith0909) reported

    @tescomobile It wasn't the signal it was due to the fact that an update needed installing. Please pass this onto your customers that are quoting similar problem with not being able to receive incoming calls, it works fine for me now. @o2
