    @O2 I need to escalate a complaint re. a member of staff who refuses to to 1) process my upgrade and 2) who has just terminated my call. Who can I talk to? Your staff say it’s not possible to talk to a manager.

  • McGuinnessKevin Kevin McGuinness (@McGuinnessKevin) reported from Belfast, Northern Ireland

    @o2 any chance you can sort out the masts in Belfast.. really slow connections and dropped connections, I’m even with o2 (was with you when it was BT Cellnet) I’m with sky who use your network but I know of o2 customers having the same issues. #o2network

    @O2 I've done that and it's still not working!

  • hughjahfink HughJahFink (@hughjahfink) reported

    @O2 The mast at SE15 that is down has been down / intermittent for possibly 5+ years. It always says 'we're working on the mast'. I've asked before, but how long until it's done? Another 5+ years?

  • tweepy_pie Dina Parmar (@tweepy_pie) reported

    @O2 @bcxllis Having issues with my o2 priority odeon. Second week running now!

  • _EmilyDrew Emily Drew (@_EmilyDrew) reported

    @O2 Thanks - none of that has worked and I cannot call 202 as have no signal. Have you got any other suggestions? Can someone look into my account etc.

  • tedsanders53 Ted Sanders (@tedsanders53) reported

    @bryony_xxx @O2 @GreggsOfficial Greggs and O2 either don’t want to make this issue public or don’t know what the problem is. Something is wrong with the scanners in Greggs which is preventing them being able to accept the o2 codes (presumably they are refusing to type the codes in). Perhaps try being honest??

  • NStupps Niki 🦼💕🇺🇦 🏴‍☠️ (@NStupps) reported

    @O2 I am still without any signal at home, which I rely on for my lifeline! I messaged you on 13/01/23 and was told it was being looked into but it’s still not resolved and I’ve had no updates! 12 days without service is NOT acceptable! Disgraceful service

  • stupotcollier stuart collier (@stupotcollier) reported

    @O2 Me still awaiting support and replies from you

  • itspaulactually Paul (@itspaulactually) reported

    @jibbajabbasteve @O2 Let me guess, you've got 4G/5G yet can't connect to the internet at all? Had this issue for months and they gave me spiel about the masts. It's a nationwide issue, especially in built up places. In the end they agreed to tear my contract and let me leave thankfully.

  • b3n4ndy Andy Benson (@b3n4ndy) reported

    @O2 what is actually wrong with your service? After taking over 10 days and 15+ hours of calls to customer service you finally finalise a number port only to send a text today to say it’s been reversed. What the hell? Fix it now!

  • jibbajabbasteve Steve N (@jibbajabbasteve) reported

    @itspaulactually @O2 no this is more signal drops and distorted calls and just generally poor. And when you check various masts where these are been used masts just say they are been worked on. For example, 2 masts in Thorne, Doncaster, both show the same
