    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

  • MaryNT16 Mary N-T (@MaryNT16) reported

    @O2 I note that you have quietly updated the website to say the price includes the saving. At least future customers won't be duped. Don't worry. I took a screenshot of the original page & included it in my @ASA_UK complaint.

  • matthewclucas Clucasmw (@matthewclucas) reported

    My wife has been chasing @O2 everyday since Thursday to obtain proof of purchase for a phone on our account. Everyday they say: "oh yes we will email it." Each time nothing. #Fail Please O2 DM me or respond. How hard is it. If it's difficult don't promise to send confirmation.
