  • 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 @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.

    What is it with companies happy to give **** service? Pauline at @O2 you were lovely but the other 5 people I’ve dealt with were a shower of shite

  • imchases Chase Silverstein 🇺🇦 (@imchases) reported

    @tescomobile So I moved to @O2 and ever since I've had no issues and I'm happy with the company. It's kinda sad how it has turned out. Because I did like tesco's but to get a near enough £900.00 debt (Which is £100 of a Macbook Air) is shocking. That's why I paid it off and moved to @O2.

  • dave_c83 David Connolly (@dave_c83) reported

    Got through to @o2 absolutely brilliant customer service. I think @virginmedia could learn a thing or two.

  • JG_UTV JG👨🏼‍🍳⚽️ (@JG_UTV) reported

  • SewManyFriends Sew Many Friends (@SewManyFriends) reported

    @O2 Grt service from Cheltenham store for 10+yrs. But yesterday was rubbish. Store staff without a clue. Boss called at least 5 times, but didn’t even acknowledge me. My phone doesn’t work properly now, and the store don’t answer their phone. O2 Support also doesn’t answer 😡

  • crazyjayne007 Jayne (@crazyjayne007) reported

    @O2 I’m trying to use the free Apple Music for five months but getting errors to manage payment. I can’t proceed without agreeing to pay £9.99 from the 1st March when it should be free until 1st of Aug.
