  • tobyd360 Toby (@tobyd360) reported from Farnborough, England

    @O2 I’m stuck! Trying to upgrade online, on the last screen realised it was the wrong GB model of iPhone 11 - seemingly can’t cancel it from there myself? And if I go back and click to upgrade again, it just brings up the load screen forever 🙁

  • 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.

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • 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 !

  • owengmusic Eoghan (@owengmusic) reported from Bracknell, England

    @o2 Ive transferred over to another network but I cant use my phone because you wont unlock it after 2 store visits (Wandsworth and Bracknell) very frustrating

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

    @O2 I need a customer call back please.

  • 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.

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUK been a loyal customer for 6 years, recently brought a new contract through you, yet my upgrade price is far from being a loyal customer, I cant even get an existing customer deal unless I take out a third contract, what a joke! Even @O2 are cheaper than what I was told

  • 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.

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • 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

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUKSupport I want the note 20 4g but was told for 30gb £58 a month with a upfront cost, where as my "customer exclusive offer" was £55 a month. Or I can can to @O2 and get 90gb for £51 a month with a less up front cost. Talk about customer loyalty!!!

  • 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.

  • JonLeePButler Jon-Lee Paul Butler (@JonLeePButler) reported from Fleet, England

    @O2 if a mast in the area is not working, and service checker gives message of 'taking longer than expected' to fix. Would ALL O2 mobiles be affected in the area? Just asking, as mine is without signal but flatmates is with. Odd that. Don't you think?

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

    Hey @O2.. I #know these are weird times. i placed an order on sunday confimed & paid. online shop says next say delivery is still available. Ive emailed, replied with please use chat. Chats off line. I phoned and only upgrades and leaving o2 calls are accepted. Help

  • 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.

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

    @O2 having problems ringing customer support from my device. Could I talk to someone in DMs please.

  • MissModette ★ Kay ★ (@MissModette) reported from Leeds, England

    @O2 can you tell me why seemingly my account with you is not closed down completely as your advisor assured me it was over the phone? I paid everything off, she said it would close down the following month (October) but today you've taken £18.83 DD from my current account.

  • ellllljaaac lorenjackson (@ellllljaaac) reported

  • GregDean5 Greg Dean (@GregDean5) reported

    @O2 Been waiting for a manager to call me for two weeks now!! Anychance? Makes me laugh how you moan yet the service you offer is fraudulent!!!

  • aimsbutler24 Aimee (@aimsbutler24) reported

    You never sent an email or texts to say you would attempt to deliver these dates either or no email to even say you had the item. It’s now back with @O2 and we’re struggling to get it redelivered but we’ve been charged for it. We’ve emailed, tried to call & tried the WhatsApp
