    @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?

    @O2 these bunch of wankers have made it so difficult to contact or speak to customer service. They promise things and don’t deliver ending up costing the customer more.

  • HBW_Scribbler Helen Watkins (@HBW_Scribbler) reported

    @O2 Twice. Did once as a turn off, turn on. Then a turn off for ten mins and then back on. Still no signal.

  • andy77nufc Andy Connelly (@andy77nufc) reported

    Is there any point to 4G+. As soon as my normal 4G flicks to 4G+ my phone goes to absolute ****. Is this an @O2 problem or do other network users suffer the same.

  • batsgonemad valiantfotography (@batsgonemad) reported

  • Natalie49233487 Natalie Brown (@Natalie49233487) reported

    @O2 my order has still not arrived?! Despatched 14th…(ordered on the 10th) DHL delay delivery every day, got email confirmation that Saturday delivery was guaranteed and it didn’t come… I’m losing patience now. I have never been so angry at such shocking service.

  • Gavin_Tansley Gavin Tansley (@Gavin_Tansley) reported
