    @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.

  • 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?

    @david_harman_uk @O2 @Ofcom Totally. Virgin is horrible company generally and not one I would ever sign up to.

  • CliveR39 Clive Richardson (@CliveR39) reported

    @virginmedia No, I have been told online and by text that there is a queue of 'at least 45 minutes'. This is NOT acceptable service. Perhaps the new partnership with @O2 might bring an improvement. I just want to ask about cancelling an upgrade.

  • Fiensey Nicholas Fiennes (@Fiensey) reported

    @O2 Day 9!!!!! Anyone going to call me???? Maybe the cleaners, anyone will do!!! Does 6.5 Billion revenue mean treat your clients like dirt???? Come on #MarkEvans give me a buzz!!! Dare you!!!

  • Beanlizard Dead_inside (@Beanlizard) reported

    @virginmedia @O2 Why don't you offer a working service then?

  • JerkSpice3 Jerk Spice Rico🇯🇲🇬🇩 (@JerkSpice3) reported

    @O2 customer service is disgraceful. Being passed back and forth because their staff are working from home and can get away without dealing with customer issues

  • SchnoopityP Schnoopity Pop (@SchnoopityP) reported

    @O2 I think someone is spoofing my number - I’ve had a few calls from different people, saying they are returning a call which appears to have come from my number, But I never called any of them. What can I do?

  • krishalpin Dyskinetic. ディスキネティック。 (@krishalpin) reported

    @O2 Hi! I have a bunch of device plans, one of which I no longer need, how do I get in touch to cancel it? It’s not my whole account, just one device

  • Maverickaizer Maverick Kaizer (@Maverickaizer) reported

    @MisterMunkie @O2 @virginmedia I’ve been O2 since the BT Cellnet era. I have never used VM, as there has always been a question mark about them. I feel this merger will mostly benefit VM… just my opinion.

  • dcowley19692 DaCow (@dcowley19692) reported

    @96Swinger @virginmedia @O2 Yes - Virgin have awful customer service.

  • BLFCxx B (@BLFCxx) reported

    @Chriss_m @Veronica_Strain @O2 I didn’t mean it literally...go online and search for complaints against them, with us they installed the router in the wrong spot and are trying to charge us 100s for them to fix their own mistake, the internet is 8x worse than we pay for also, they’re not being fined for nothin
