    @O2 I can’t sign into the app and the codes you’re sending don’t work!? Help! #suspicion #O2Priority

  • Rogue_Asset Rogue Asset (@Rogue_Asset) reported

    @happyhardwick @O2 @julesserkin cheers, a good idea 'short term', these alerts will happen later, so I want to stamp it out 100% to avoid 'random' stress for my doggo very frustrating... Q) why have the 'network providers' not text their customers to ask if this alert is ok to transmit?

  • Dharathedoc Dhara Thakerar (@Dharathedoc) reported

    @O2 Have had the *worst* customer service experience I have ever seen in the U.K via the call centre. It was disgusting. I can’t even DM as the O2 account isn’t working. In my opinion this issue has wider public interest and safety issues. Can someone in O2 get back to me today.

  • ItssChar_ char. 🤟🏼 (@ItssChar_) reported

    Why do I NEVER get internet at certain times of the day, like this whole journey to work. Nothing. Then when I spoke to @O2 CS yday she said “every company is like it”… This CS I swear! 😡 Paying almost £70 for 5G which I don’t get, I get 3G & that don’t even work. 🤬

  • AJWest0n29 Andy Weston (@AJWest0n29) reported

    @O2 my £5 carvery we code is not working

  • Lee911611 Lee (@Lee911611) reported

    @O2 is it possible to exit a sim only contract early due to appalling signal etc. ? Been back with o2 for nearly 6 months now and its constantly like being in 2003 with GPRS. Shambolic

  • FPuppiesandpals Fluffy_Puppiesandpals (@FPuppiesandpals) reported

    @O2 apparently there is a default on my credit score with O2 and I have no idea why, I cancelled my accounts last year (so no longer have an account) and everything was paid at the time so wtf has happened?

  • jamesmelley James Melley (@jamesmelley) reported

    @O2 This has been a problem for a month. I’ve been through all the ‘turn it off, turn it back on again’ options many times. I am happy to give you more details in private.

  • RozeEpUk RozeEpUk (@RozeEpUk) reported

    @O2 not impressed with the service I had 14gb left when I topped my phone up before my anniversary date and never received my new 7GB to roll over plus I received a message saying I would receive a further 10GB for being a loyal customer

  • Jules_J Julia Johnson (@Jules_J) reported

    @O2 help! You have deactivated my SIM but I have not received the QR code by email to set up the E-sim so now I have no phone, no texts. I called this morning and have the order number
