    @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€

  • 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.

  • 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?

    @O2 complaint…. Priority drinks not valid in Scotland. Presume because of govt min pricing? Please remove ‘all over uk’ and arrange something alternative for Scotland customers please

  • AntonidaMK Antonida Kocharova (@AntonidaMK) reported

    @O2 Secondly I tried the app messaging service, whereupon the assistant told me the details for flying to America, clearly never having heard of Alderney.

  • K3N_4D4MS Ken Adams (@K3N_4D4MS) reported

    @O2 @jacobmenick How can you not have a timescale at least 10 days into the problem?

  • MeliaNick Nick Melia (@MeliaNick) reported

    Yesterday I upgraded my @O2 contract and was told by the salesman on the phone that because I was a @virginmedia customer, I was entitled to a FREE upgraded on my broadband and double data on my contract. At the end of the call, I was put through to someone at @virginmedia

  • AntonidaMK Antonida Kocharova (@AntonidaMK) reported

    @O2 Any chance anyone in the company knows what Alderney is? We're traveling today, and I would quite like to know what I am going to be charged for using my phone and so far this is the customer service I have had...

  • bellenes_peter Peter Bellenes (@bellenes_peter) reported

    @O2 just switched to BT and receive threatening "Enforcement Letter" - this is the first letter and direct debit still in place. Not a good invitation ever to return. As my granddaughter said "Never going with them"..

  • AnthraXFPS AnthraXFPS (@AnthraXFPS) reported

    @virginmedia @ITVChase @O2 You lot are complete rubbish! You are fast enough charging extortionate amounts for your packages, an prices keep rising, zero discounts to old loyal customers! Yet you still seem unable to keep internet stability a priority, and your call centres are a joke.

  • Souvenir_AJ ♥Andrea Jayne ♥🇺🇦 (@Souvenir_AJ) reported

    @virginmedia @ITVChase @O2 My connection isn't down yet but I can't sign into your website. When will it be back?

  • loveyou3000muah Sparkle (@loveyou3000muah) reported

    @virginmedia @ITVChase @O2 The internet service is down now?

  • MrStanBrooks Stan 💙 (@MrStanBrooks) reported

    Replied to @O2 regarding my complaint two weeks ago and had no reply since. How long am I expected to wait when the service you’re providing is still rubbish?
