  • 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.

  • 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

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

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

    @O2 simply dreadful customer experience tonight -felt really let down

  • 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

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

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

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

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

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • AEgbuonu ARIBBUZZ (@AEgbuonu) reported from Welwyn Garden City, England

    @O2 sort your cancellation team and phone problem out. #poorcustomerservice

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

Latest outage, problems and issue reports in social media:

  • Lynbodegas recrudescence! 😱(look it up!) (@Lynbodegas) reported

    @MartinSLewis @O2 has never kept their contract in Guildford. Walk outside my door, no network. They even gave me £50 after admitting there is no 5G in Guildford-they have constantly lied to their customers!!

  • P_C_Pickstock Phillip Pickstock (@P_C_Pickstock) reported

    @MartinSLewis @GMB @o2 25% increase for a SIM only contract is unacceptable, also I don't understand why new customer deals are much cheaper

  • xnikkixpetex Nikki & Pete (@xnikkixpetex) reported

    @darrenjwood @O2 @AXS_UK Yes we had a look at Manchester to see if it was working so seems to be an issue with the indigo2 link. So annoying!

  • Paulharvey16 Paul Harvey (@Paulharvey16) reported

    @O2 over 4 hours to get a PAC code to instigate my right to cancel (due to your unfair increase) then a phone call to support (on hold for 30 mins) get through and you cut me off. This is disgraceful customer service from a loyal customer of over 20 years. @MartinSLewis

  • WildJyy Jayden (@WildJyy) reported

    @O2 @AXS_UK @TheO2 when you go to enter a waiting room for Westlife at the O2, it takes you to the generic AXS site. Think there's issues on your end.

  • edin_chauffeur Cheesed off chauffeur (@edin_chauffeur) reported

    Looks like it's adios to @O2 after 17 years of being a loyal customer. Cost of living is hitting us all and im not tolerating pure corporate greed. Looks like @tescomobile will be getting my business for a while.

  • laaur3nxox Lauren 🖤 (@laaur3nxox) reported

    @O2 hello, i have received an email advising i am eligible to cancel my airtime plan early. can you please advise how i go about this thanks.

  • xxxsammiexxxxx sammie (@xxxsammiexxxxx) reported

    @O2 think your having issues with westlife presale can’t seem to get into the queue

  • philipscott20 Phil (@philipscott20) reported

    @O2 @TicketmasterUK as plenty others are saying , the presale process is a **** show. 8:45 to join waiting room - error , get in and 45k ahead of me , wait 50mins to get through then the pages doesn’t open and end up back in a queue with 46k ahead. Charge top money , poor service

  • EdisonMalick Edison Malick🇹🇹 (@EdisonMalick) reported

    @MartinSLewis Dear @O2 I will under any circumstances be paying above what my contract says. I will personally go to a store & it’ll be a problem just so you know in advance. Kind Regards
