    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

  • skbarrone Sarah Barron (@skbarrone) reported from Fingal County, Leinster

    @O2 Thanks. Problem started in London but same in Dublin. Everything works fine on Wi-Fi.

  • GlacierShazada ShazadaGlacier (@GlacierShazada) reported

    @CitizensAdvice @o2 for me not to be able to cancel my subscription from the o2 website or the @disneyplus app/ website, is this not a subscription trap? On Disney I’m referred to O2 where I’m able to upgrade very easily, add on extras easily but to cancel and view- impossible

  • glenry Nicola Chalmers (@glenry) reported

    @O2 To pay even though I haven’t used them as EE didn’t complete the port of numbers until the 13th. I’ve explained the reason I had to leave was because I couldn’t use them as no signal but she just kept repeating herself but I don’t know if she didn’t understand

  • tete_blanche Mike W (@tete_blanche) reported

    @O2 want to cancel my contract, can I do this online or still have to phone up like the old days and be on hold ages?

  • MW1CGG JamesB 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@MW1CGG) reported

    I have the best e-mail address in the world for my name. Had it since the 90s. @o2 are the only ones that won't accept it because their e-mail validating code is crap. I had to create an alias because they won't accept only one character before the @.

  • Aruuj_x Aruj (@Aruuj_x) reported

    @virginmedia Tried to ring your CS team they won’t let me speak to a senior manager to get my deadlock nor provide me with anything to show they are dealing with my case. Complete waste of time and ridiculous way to treat a customer who’s coming from @O2 .

    @O2 Can I please get in touch with someone about reconnecting my service?

  • joeIIlll Joel (@joeIIlll) reported

    @O2 any issues in the Manchester area? Got 1 bar

  • GlacierShazada ShazadaGlacier (@GlacierShazada) reported

    @O2 I’m here because I can’t view it at all. Every time I try to find it, the website just goes to my bill where there’s a break down of charges but it has no where for me to cancel the monthly charges or see what it’s for.
