    @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?

    @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€

  • netsmith chris aldridge (@netsmith) reported

    Hey @O2 you seemed to have doubled my mobile bill this month for some reason, does that mean I now have to spend 2 days fighting with the 2nd worse customer service (after @virginmedia ) in the country?

  • AnnaGordonPics Anna Gordon (@AnnaGordonPics) reported

    Third working day unable to receive calls and text messages to my phone, 7 calls to customer services still not working. Not great for a freelance photographer @O2

  • TinkMissy Missy Tink (@TinkMissy) reported

    @O2 And I’m sure that you can see from your reply on 25th November that my issues still haven’t been addressed, how long this had been going on for and how incompetent you are. Would you like me to post the screenshots here to refresh you?? @o2

  • sennaf15 Paul Rawding (@sennaf15) reported

    @O2 Fix your shockingly bad internet service

  • sunshineinwelsh Heulwen (@sunshineinwelsh) reported

    @O2 The items in cart were all from the linked section. The problem wasn’t that it wasn’t taking the discount off, it just wouldn’t accept the code to apply to the cart. In red it said “Oops! The promo code you entered is invalid. Please check the code and try again.”

  • Gr8Customer Dan G (@Gr8Customer) reported

    @O2 @LutzSchueler @Trustpilot See my feed for detail on O2 not being helpful, not calling back, hanging up on me and making me drive to a shop for no reason. Still no network service.
