  • 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.

  • 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

  • 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

  • ScottCanEat ScottCanEat (@ScottCanEat) reported from London, England

  • 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.

  • 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 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.

  • 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.

  • 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 !

  • 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.

  • 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

  • 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.

  • 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!!)

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • Original_MrC Ciaran Murphy (@Original_MrC) reported

    @O2 tried to login to Perplexity Pro having redeemed the free offer a few months back, but it’s not letting me login. The page on the Priority app shows it’s been redeemed?? Any chance of some help to sort this please?

  • liammjwhite Liam White (@liammjwhite) reported

    @O2 you sent me an email saying i 'd get a free welcome gift (worth up to £89.99) if i downloaded the priority app. I've done so and am not getting anything relating to a free goft. Can you help advise what I need to do to claim my gift please 🙏

  • RachT234 RachT234 (@RachT234) reported

    I’ve since moved to @O2, who responded helpfully, respectfully, and actually listened — even when I had no service and had to rely on a family member’s phone (without Relay UK, and with encouragement). This outage was caused by Three failing to provide porting info, leaving me without service for around 10 hours. In contrast, Three left me feeling ignored.

  • Clairejadex Claire Marsh (@Clairejadex) reported

    @O2 hi currently abroad and suddenly have no service ??

  • AWKrey Andy (@AWKrey) reported

    @O2 what the hell is going on? Full 4G signal and can barely refresh my Twitter let alone watch the F1 qualifying.

  • V_D_Onofrio Vincenzo D'Onofrio (@V_D_Onofrio) reported

    @O2 I have a business account. No voice or data service for 2 hours. Over the past month, your service has been increasingly unreliable. Is there any compensation for this? Can I terminate the contract early without penalties? #O2down

  • Brian36989521 Brian (@Brian36989521) reported

    @O2 say hello to zero network in Britains second city this weekend again and remind me why i pay you big bucks every month and have to use someone else’s network and devices to communicate?? You never answer so i think i know the reason

  • lwong6053 Lily Jones Wong (@lwong6053) reported

    @O2 reception very poor at Wimbledon. Not good.

  • ddphotograph Dominic DEAN 📸 (@ddphotograph) reported

    So i have been with @O2 for over 30 years and the signal now is worse than ever. Recommendations please for mobile provider?

  • technicslover Technicslover (@technicslover) reported

    @dealatrip @DanielJHannan I find it hilarious how @O2 cover their shops in Pride **** isolating many potential customers then instantly have a sale to get them back on the 1st of July :)
