    Hey @O2 @giffgaff you say there's no issues and that you're keeping an eye on an issue you fixed well me and my friend are still having issues with mobile data and texts, we've restarted our phones, we've tried to all other methods and nothing has worked.

  • m_mxrtha 💗 (@m_mxrtha) reported

    @O2 the Tony’s chocoloney link is broken

  • jenny_9388 Jennifer Taylor (@jenny_9388) reported

    Outstanding customer service from Conner at @O2 in Dumfries last Sunday. He really needs to receive some recognition as he was the definition of above and beyond in helping sort a phone issue for partner’s 90 year old dad. O2 - please recognise and reward! He was a credit to you!

  • P5ych1cPoet Name (@P5ych1cPoet) reported

    @virginmedia @O2 Don't know how long it's been like it, mostly a lose of connection. Even the *#10# dial code is broken. Having to sign in to My O2 suddenly the verification required a certificate install, while I've managed to now gain access to My O2 the sub menus are lose of connection. 🤷

  • king_clayton clayton king (@king_clayton) reported

    @O2 your mobile coverage is diabolical, 5g but doesn’t do anything 4g doesn’t do anything then it goes 3G and that’s non existent- all on train from Waterloo to west byfleet- imagine needing you in an emergency

  • atmemaynnn Kay Marie (@atmemaynnn) reported

    @O2 it definitely seems that with over 600 iPhone (allegedly) gone missing that’s a big issue for o2 and @Apple that’s nearly £1,000,000 …

  • _FootyLad Connor (@_FootyLad) reported

    @O2 Jesus, I’m speaking with an agent & he’s actually so rude.

  • maaverix Ge🎃S (@maaverix) reported

    @Paul_Reviews @O2 Why is the cell coverage across most networks so poor?

  • intergeri Vagina Coastguard🏴󠁧󠁢󠁳󠁣󠁴󠁿🏳️‍🌈🏳️‍⚧️ (@intergeri) reported

    @O2 So AI or calling you which, as I'm neither a Virgin or O2 customer , will probably cost me money. Is there not an email address i could contact. We are talking about possible fraud. @virginmedia
