  • CorinaWieland Corina Wieland (@CorinaWieland) reported from London, England

    @VictoriaGoodyer @O2 Exactly what I will do! I was hoping the more expensive monthly rate (to other providers) is justifid by the costumer service. How wrong was I! Fed up with the poor service, signal cover (in London!), weekends without data and now this.

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @O2 It doesn’t work. Back doing same lose of signal again. Happens at random places and times around london. Seriously thinking of switching back to #Three

  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • Ali_Malik Ali Malik (@Ali_Malik) reported from London, England

    The ordeal continues. @O2 and it’s #CustomerService is very good at taking notes but appalling at resolving complaints / closing issues. Generated an incorrect / inflated bill despite multiple assurances otherwise! Now running pillar to post, no resolution in sight @MarkEvansO2

  • HaleAlexander Alex Hale (@HaleAlexander) reported from London, England

    @O2 @RugbyXOfficial What a shit show the organisation is at the O2 tonight.. #nopoint

  • AbbeygaleRose 𝐀𝐛𝐛𝐞𝐲𝐠𝐚𝐥𝐞 (@AbbeygaleRose) reported from Chelmsford, England

    Beginning to regret renewing my contract with O2, their coverage in Chelmsford is awful. My 4G works about 20% of the time. @O2

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • HarvsTheDuck Dan Harvey (@HarvsTheDuck) reported from Rayleigh, England

    @stu_levy1 @Luca__WFC @O2 I've just realised that might be Rick Astley on stage as the support act, sorry.

  • 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

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @cleggytaxi @O2 Yep you’re right. Signal dropped again.

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • EmRosePull Emmss (@EmRosePull) reported from Chelmsford, England

  • CorinaWieland Corina Wieland (@CorinaWieland) reported from London, England

    @O2 I have called O2 several times and also chatted online to a few people (Nooruddin for example).I also spoke to the 3rd party which don’t care and to the police which are busy with bigger problems.What it comes down to is YOU are charging me, and I am YOUR costumer

  • RoslynBriggs89 Roslyn (@RoslynBriggs89) reported from London, England

    @O2 is one of the worst phone providers. How can I pay off my contract and still get charged. Your website is overcrowded too. Disgusting and poor service.

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

  • rightwingback Ryan (@rightwingback) reported from South Woodham Ferrers, England

    @O2 I hope I'm gonna have a discount in my phone bill this month for your network constantly being down

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

  • NFProtogen NF Protogen (@NFProtogen) reported

    I know this is most likely an error with my ****** @O2 signal but it made me chuckle

  • MrAHarrisonCS Mr Harrison, Head of Computing #loveteaching (@MrAHarrisonCS) reported

    I am furious with @O2 - you cut me and all four family phones off last night with no warning due to "unusual usage", yes we were in the US and I told you at the beginning of the holiday and raised the price cap accordingly! How dare you demand £218 immediately to restore service.

  • EmberInns Ember Inns (@EmberInns) reported

    @thekinaton @O2 @mbplc Hi Jason, we were informed there was a slight technical issue which lasted around 15 mins and we're pleased to advise this has been resolved. Apologies for any inconvenience this caused you at the time. CP

  • zanda01 Alex Hibbert (@zanda01) reported

    @O2 I’ve tried the Thursday Thursdays code the last two weeks and it doesn’t work at all? Any help at all?

  • djbsuffolk Dave Bagnall 🇬🇧 (@djbsuffolk) reported

    Loyal @O2 customer here - if you're thinking of switching to them don't - infrastructure unfixed for over a year, despite the 'team being aware' and an over 11% price increase.

  • MrAHarrisonCS Mr Harrison, Head of Computing #loveteaching (@MrAHarrisonCS) reported

    @O2 This whole episode has rocked my confidence in @o2. You've treated us appallingly and are still refusing to see it. I'm not a debt risk. You can see that. My usage was understandable, you can also see that. Your process is broken and unacceptably distressing.

  • thekinaton Jason Sensation (@thekinaton) reported

    @EmberInns @O2 @mbplc Doesn't help me. Now my voucher has expired.. Terrible.

  • realpetetwm Pedro Griff (@realpetetwm) reported

    @O2 priority offer not working in Ember inn saying QR code invalid

  • lakhan_prince Da Prince (@lakhan_prince) reported

    @O2 hi am so fed up with o2 and all the lies I have been told and the rude advisors tbh nobody gets back to you people the service is so terrible and all they are after is your money

  • lapinoscaseylee Pand'Assassin (@lapinoscaseylee) reported

    @O2 please don't use DPD for delivery. They're the worst. I need a refund for next day delivery fee on my new phone. Who can I speak to? Thanks
