  • 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!!!

  • 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

  • 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.

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

    @O2 dm pls. I have a problem

  • 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.

  • akasha303 Greg Meeres (@akasha303) reported from Twyford, England

    @O2 Your web chat support team advised I ‘needed’ to call Equifax, rather than Experian, even when I queried (as I have an Experian account). Might want to check the process playbooks! (Issue is now resolved through a work around).

  • 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.

  • 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.

  • 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!

  • 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?

  • 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

  • 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.

  • 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

  • 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

  • Ricardo_7united 🔻ᏒᎥፈᏂᏗᏒᎴ ᏕᏗᏁᎴᏋᏒᏕ/Ⓡⓔⓓ ⚽️🥅🎮🍪🍻 🔻 (@Ricardo_7united) reported from High Wycombe, England

    @sophdefoe92 I had that problem on @O2 but managed to sort it out

  • 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.

  • 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

  • SaintGeorgie Georgie Tongue (@SaintGeorgie) reported from Wokingham, England

    @O2 I spent hours on chat to your advisers trying to cancel my phone contract and was told it was all done. I started a new contract with another provider and now suddenly I have been started on a new o2 tariff??? Help!

  • 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.

  • ninavdbennett Nina Van Driel (@ninavdbennett) reported from Windsor, England

    @O2 I am sorry but I am simply shocked at your poor customer service. I have now called twice to complain and ask for help. Twice I have been told a manager would call me. Twice this has not happened.

  • Ryceryce Rhianon McAulay♀ (@Ryceryce) reported

    @O2 I have no data!!! My bills paid help! I have no 4G! What am I paying for! Xxx

  • KevinCu69079772 Kevin Cullen (@KevinCu69079772) reported

    @O2 @JamesFlett4 O2 when are you planing to set this up, seems ridiculous that a personal customer has better privileges than a business customer. What is the reason for this failure to your loyal business customers ??

  • mrslizzycook liz cook (@mrslizzycook) reported

    @O2 hi, I sent a DM yesterday but still no response, can you help please?

  • jaymietsmith Jaymie Smith (@jaymietsmith) reported

    I’m shocked with the poor signal service of @O2

  • uncriticalsimon Simon 💉💉💉🐉 (@uncriticalsimon) reported from Newport, Wales

    @jasonmackenzie @O2 OK I once had trouble with EE (not for the mobile service but when I switched to broadband), it got so bad that I decided to go back to Sky. (NB now with TalkTalk, also not great for customer service but OK if nothing goes wrong.)

  • MunozSaiz corinne munoz (@MunozSaiz) reported

    @O2 hi I received a text yesterday to say my direct debit has been cancelled, I tried to call but couldn’t get through. You now appear to have cancelled my account . I now can’t call as I have no signal, I tried WiFi calling too and that doesn’t work can anyone help

  • cassieperryman Cassie Perryman (@cassieperryman) reported

    @MacandTG @O2 Same issue here!!! Still no SIM, being charged while waiting for it, order says complete!!! Have requested a replacement but again the tracking number isn’t recognised and O2’s own tracking is again stuck at ‘processing’….

  • jasonmackenzie Jason MacKenzie (@jasonmackenzie) reported from Merton, England

    @O2 Do you think it will be today, tomorrow, Monday? A rough indication would help. Please would you also advise if I can cancel the contract and phone altogether with no penalty? Right now, it would be much easier for me to just stay with @VodafoneUK than to move to @O2.

  • ChloeWD38 Chloe Marie WD (@ChloeWD38) reported

    @O2 how do I file a complaint for harassment from your shocking business? #O2 #ArrearsNotice #Section86B NO DEBT. Constant letters sent to me in the post! Can anyone advise? I am not standing for this!!!

  • jasonmackenzie Jason MacKenzie (@jasonmackenzie) reported from Merton, England

    @O2 It’s very frustrating. The delivery yesterday didn’t arrive, then @DHLParcelUK (falsely) claimed they couldn’t get access. I went into an @O2 shop just now - they said I had to ring customer services. I spoke with someone who said they’d help, and the call dropped after 16mins.
