  • ConlethKane Conleth Kane (@ConlethKane) reported from Hounslow, England

    I’ve been with @O2 for 7 years. I’ve been trying to negotiate an upgrade over the past 24 hours and it has been an actual nightmare. Really bad customer service.

  • JoeAchilles Joeachilles.com (@JoeAchilles) reported from Denham, England

    Mother has been getting scammed by a mobile app service "Lasevia limited" for past 8 ish months, her mobile provider @O2 can't help at all. Looking online this has been an issue for ages yet nothing has been done by O2 😡

  • RossBrown1_1 Ross Brown (@RossBrown1_1) reported from Wokingham, England

    @O2 @TheO2 “We’re better connected” “Be more dog” only thing dog is your service

  • AnnKerridge Ann (@AnnKerridge) reported from Wokingham, England

    @O2 It'd nice to see that o2 take customer complaints seriously! Just as about as seriously as using there o2 guru chat service!! I'm still waiting for a reply to my DM that I sent you over an hour ago (about the length of time I wasted on the guru chat service!!)

  • Avigazed Avigazed (@Avigazed) reported from Addlestone, England

    @O2 How long does it take to port a number from another network to o2? Surely 2 days is a bit long.

  • ShahlaaTahira 💟 (@ShahlaaTahira) reported from Hillingdon, England

    So now I’m without a phone and will never know where or what happened to my iPhone all because of poor customer service from Hassan in the @O2 Lewisham Branch! So much for customer service! #disgustedcustomer @BBCWatchdog

  • 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”.

  • ukcomic Jeff Stevenson (@ukcomic) reported from Hillingdon, England

    @VodafoneUK I have spent three hours of phone time trying to resolve a mistake that your company has made. I am so glad I went back to @O2 PLEASE BE WARNED .... Vodafone customer service is the worse !

  • oliviakhwaja Olivia Khwaja (@oliviakhwaja) reported from Sunningdale, England

    @O2 great marketing activity. But no good doing that if you can’t provide basic service. Have been trying for 2 weeks to buy a new SIM. Passed around everywhere, 40 minute waits, given phone numbers by your South African call centre that don’t work. Not feeling like centre stage.

  • bukachef Fine Chef Damilola🥰 (@bukachef) reported from Harrow Weald, England

    @O2 dm pls. I have a problem

  • ShahlaaTahira 💟 (@ShahlaaTahira) reported from Hillingdon, England

    If your an @O2 customer be careful I’ve had emails and texts saying I owe my bill and I checked through my App and I don’t owe anything. #FraudAwareness

  • 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.

  • bethanyxhewitt Bethany Hewitt (@bethanyxhewitt) reported from Bracknell, England

    Experienced some of the worst customer service to date!! First the advisor takes £400 more than agreed, next I’m chasing advisors everyday for a month with false lies about refund dates @o2 #notacceptable

  • love_kittyket Katherine Stephens (@love_kittyket) reported from Hillingdon, England

    Trying to contact @O2 about my bill. But your live chat unavailable, your phone service is limited and cuts me off and my O2 app not useful in helping me.

  • itsnadine_ abena (@itsnadine_) reported from Harrow Weald, England

    @O2 I changed my tariff now I can’t add a bolt on, if I can’t listen to this mix whilst on a run I’ll cry help

  • maryhippychick m a r y (@maryhippychick) reported from Hounslow, England

    @O2 I phoned up customer services who passed it onto the fraud department. They ( customer services) were extremely understanding. I haven spoken to your fraud department.

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 I need a customer call back please.

  • maryhippychick m a r y (@maryhippychick) reported from Hounslow, England

    @O2 It’s being investigated but there was no indication that they would be back in touch with me. I’m concerned that my address will show up with bad credit with both you and other bodies as a result of this fraud.

  • Wally18896684 Wally (@Wally18896684) reported

    @O2 Yes, the code was presented within the time window and was visibly counting down even though the barrista was telling me it wasn’t being accepted. The code wasn’t showing ‘used’ until long after the incident

  • Adamkeeble Adam Keeble (@Adamkeeble) reported

    @O2 You need to make proper charges so you can bring back your customer services in the UK - 3 calls to your useless oursourced call centre and still no closer to resolving my problem. All they can do is read a crib sheet and put one on hold for 20 mins at a time. Absolutely hopeless

  • j0wh1te jo whitehouse (@j0wh1te) reported

    O2 are an absolute disgrace poor customer service, poor network had nothing but trouble with this network for 4 months phoned this morning and said they will send new sim out and now tonight I have no network at all as @O2 have turned it off before new sim arrives

  • willconway66 will conway (@willconway66) reported

    @virginmedia I've just renewed my contract for ultimate volt bundle, I'm happy with VM services but @O2 services are so poor speed and reception wise. My question is can I cancel my O2 sim and still pay you the discounted price or will I lose all discount on the account?

  • j0wh1te jo whitehouse (@j0wh1te) reported

    @o2 leaving me with no service, I need my phone for emergency as two vulnerable in my home who I care for,why would you even turn my phone off when sim isn't here and can take upto 3 day??? Bet you don't forget to take my monthly debt though... fuming o2 are a joke
