  • 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

  • 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

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

  • 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.

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • 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

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

    @O2 I need a customer call back please.

  • 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

  • KevinWNewman Kevin Newman (@KevinWNewman) reported from London, England

    @ianvisits Pointless arguing against the machine 🤖! Take your business elsewhere Ian. I’m sure @EE or @O2 will be willing to help out!

  • 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.

  • 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”.

  • 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.

  • 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.

  • 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.

  • 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 !

  • 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.

  • UnityCathal Cathal O'Sullivan (@UnityCathal) reported

    @O2 - please help o2! I've gotten locked into an additional phone contract and now paying two airtime/device payments each month. Is there a way to stop airtime payment on the second device as the device is not functional? ie - I'm paying for a service that I cannot access?

  • matt_brewster7 Matt (@matt_brewster7) reported

    @O2 It's non-use then , I needed it tomorrow . That's the only reason I agreed to the up grade . Your staff are also quite Rude when I tried to cancel the order as you've mis sold it to me . I've logged a complaint and I wish to take it further. I'd advise everyone to avoid 02

  • stuart_fenton Stuart A Fenton (@stuart_fenton) reported

    Interesting email from @O2 regarding roaming. Previously your contract data package (unlimited in my case) was available across Europe and USA. Now capped at 25gb per trip. Vodafone doing the same. This is crap for biz travel, worse for family holidays

  • MrGarySmith Gary Brian Smith (@MrGarySmith) reported from Dartford, England

    @virginmedia Furthermore I’ll not be renewing my @O2 contract when they merge with Virgin bad enough with on #showerofshit can’t be dealing with it on my mobile as well.

  • Life360 Life360 (@Life360) reported

    @SparklyG @O2 Hi, we are not seeing the DM from you. Can you please send another DM to Life360 only with the email address on your account and a description of the problem? Looking forward to hearing from you soon. Thanks! ~Kris

  • Scrumpyjen87 Jen Fielder (@Scrumpyjen87) reported

    @AndyNayler @TalkTalk Same here Andy. I had about 3 hours of connection and then it cut out again. It's a good job I've got a good @O2 data plan as I'm having to use that to work from home rather than my actual Internet connection!

  • simonhall1974 Simon Hall The Infamous Infant ❤️✌🏻📷🏉☕ (@simonhall1974) reported

    have had shocking service over the last few days from @O2 however @ThreeUKSupport have restored my faith in Mobile networks and also saved me a truckload of cash in the process. superb #CustomerService from them would recommend for sure

  • jwayne_1972 Jayne (@jwayne_1972) reported

    Hoping someone at @O2 actually responds to my partners complaint and resolves the issues ASAP. Have sent a DM as a last resort! Please check

  • AbieeOliver Abiee Oliver (@AbieeOliver) reported

    @O2 why can’t I change my password? It’s asking me for my first school that I attended and it’s saying it’s not the answer I provided, when I clearly remember what school it was! I tried my last 4 bank card numbers and it still wouldn’t accept! Help, please!

  • bullyathome Leigh Bullimore (@bullyathome) reported

    @itsonlymeruth @O2 No, when I called O2 customer services they were adament this wasn't happening and if I wanted to leave I'd need to pay my early termination charge... Will be trying again today...
