  • tleach84 Tracey Leach (@tleach84) reported

    Just been into @O2 and had appalling service. First time this has ever happened in my many years being a customer. Even considering not renewing my contract. If anyone knows of a mobile service who do family plans let me know

  • Godzilla4761 Godzilla (@Godzilla4761) reported

    After almost 20yrs as an @O2 customer I will shortly be moving to a new provider. The preorder experience for the iPhone 17 on Friday was the last straw. After trying for 7hrs with o2 I was able to preorder for release day with another provider in under a minute. And to top it off I’ll save £20 a month for the same contract

  • AmySmit46258497 Ami (@AmySmit46258497) reported

    Go n buy my son a £15 pre loaded pre pay 02 sim for it not be activated properly then them to say on the phone he needs a card to be added to his account to activate it and give him 3 months for free? Why’s this been so difficult? 4 contracts with 02 and never again @O2

  • TheCyberPsyche Dr Dawn Branley-Bell (on 🦋 @thecyberpsyche) (@TheCyberPsyche) reported

    @O2 I have had an official complaint lodged with you for months. The sim you are charging me for has never worked. You said you would call to cancel it but you never call and if i try to contact you your team can’t help. Yet you continue to charge me. Sort it out quickly please.

  • ElCapitan1979 Sheikh Abdul Falafel (@ElCapitan1979) reported

    @TheO2 @O2 @virginmedia **** off Crashed broken logged out. I am leaving 02 after 15 years

  • BBManik B.B. Manik & The Lightning Powered Manatee (@BBManik) reported

    The service I’ve received from @O2 has been so bad that I’ve decided to move to a different provider. If anyone can recommend a network with good coverage in north london, I’d appreciate it.

  • benjaminlfc Benjamin Webster (@benjaminlfc) reported

    @BPCP91 @O2 Yes and it says this part of the order has been sent and can’t cancel. Some as someone else has mentioned have got DPD notifications in the DPD app. I haven’t but they also use DHL as a courier

  • jillybl1234 Jill (@jillybl1234) reported

    @O2 hi I am having issues trying to log into “my o2” app. It keeps taking me to the virgin media to link the 2 but the email address is not correct to connect them.

  • JoannieO Joan Donaghy (@JoannieO) reported

    @O2 I am having the same issue as before with the Lewis Capaldi this time with @gorillaz. Trying to get a ticket for my 19 year old. I need your help plz 🙏

  • TheRatters Neil Askew (@TheRatters) reported

    @O2 pretty poor customer service when all I’m asking for is to increase my mothers call minutes on her monthly contract as she is currently in hospital with a broken leg and all you want to do is sign her up for another 24 month contract!
