  • 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!

  • 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!

  • 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.

  • 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

    @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

  • 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!!!

  • 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).

  • 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.

  • 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.

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    Hello @O2 I am back 🙌🏻 after a few years with no signal, awful service I have come back with my tail between my legs 🙈 #ohtohavesignal 🥳🥳🥳

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

    @O2 dm pls. I have a problem

  • 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?

  • 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.

  • 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.

  • 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

  • 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

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

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

  • 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

  • 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.

  • garethenglish86 Gareth English (@garethenglish86) reported from Eastwood, England

    @EE currently having issues with an s21 ultra and galaxy watch 4 4g on @o2 (bear with me here) if I buy a galaxy watch 4 4g from EE with a data plan and get a mobile data plan for the s21 can they both use the same phone number? O2 can't seem to help me solve this issue.

  • ninsey_t janine (@ninsey_t) reported

    @O2 Why is my local area experiencing frequent 9hr long blackouts of no phone or 4g/WiFi signal? I'm paying for a service you aren't reliably delivering! Its incredibly inconvenient!

  • boulezian Mark Berry (@boulezian) reported

    Hi @O2. I have an urgent problem I need help with. I am out of the UK and have no Internet connectivity on my phone. I cannot find anyone to speak to by calling 202. Would you be able to help me, please?

  • HarryGarside Harry Garside (@HarryGarside) reported

    Any idea what’s going on @o2? Haven’t been able to use my data all day. Been in London and Kent so I don’t think it’s a local outage.

  • dave_fincham Dave Fincham Photography (@dave_fincham) reported

    @O2 Tried these over the course of weeks. I have direct call to your specialist team. I am paying £50 month with no service. I am tired , angry and anxious now. Promised call backs, nothing happens. @O2 @MarkEvansO2 #cancelmycontract #o2service

  • garethenglish86 Gareth English (@garethenglish86) reported

    @O2 @SamsungUK Not a single person in customer service can help set my watch 4 with esim to the same phone number as my phone even after an hour on the phone! Any help please?

  • MrTegSingh Teg Singh (@MrTegSingh) reported

    @Officialunoffi5 @wolvesclaire @O2 Never had this problem before now sorted and got my phone

  • _Lizzie_03 𝕃𝕚𝕫𝕫𝕚𝕖 (@_Lizzie_03) reported

    @O2 Specific areas LU3 3HP is the worst It drops out from full signal to 1 bar and then E not even 3G! No doubt you’ll tell me you are doing maintenance works

  • SarahThirlaway Sparkly Sarah (@SarahThirlaway) reported

    @O2 can you please help I need to speak to someone on online chat but I can’t find it on your site anymore

  • quigdes Kevin Quigley (@quigdes) reported

    @philchamp_ @O2 @ThreeUK We were looking at all the options but the promised 20% discount tipped the balance back to O2. But like all these things it is a con. You have to "claim" the discount after you sign up. Well all I can say is O2 just lost me and the business as a customer. Truly fed up with this.
