  • ColinShaw_CX Colin Shaw (@ColinShaw_CX) reported from London, England

    Unbelievable. I get a survey from @O2 regarding their service. I say it’s poor. They contact me and suggest a SIM card change. They have now cut me off until new SIM card arrives! For 3 days! O2 store can’t help. What a shambles! #cx #fail

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Walthamstow, England

    @O2 Please don’t tell me this mast is still not fixed. Again sat at Liverpool Streets Station with full service and 4G and nothing happening on phone full stop. Time to accept that coverage here is not good enough.

  • BrianJThompson8 BrianJThompson8 (@BrianJThompson8) reported from Barnet, England

    @ItsAdsolution @O2 All of my calls which I've tried to make the O2 have not been answered I have a 40 phone and they don't seem to care I think if this keeps on we should see them because I've got a really bad disability and I've got a 40 phone so we should sue them

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

  • 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

  • CerviF Fran (@CerviF) reported from Walthamstow, England

    I have just had a text from scammers pretending to be @O2 telling me there was a problem taking payment. They asked me to click on a link to confirm bank details. I didn’t. I deleted the text. Please RT and help others.

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • Gigiryche Gianluigi PAGHI (@Gigiryche) reported from Harrow Weald, England

    Thank you @o2 for telling me now that you can’t solve my issue with @Apple Watch because “it is not a necessity device”. However when you publicised the deal “AppleWatch plus iPhone”, at the time of my purchase no one at the store mentioned “it’s not a necessity device”.
