  • nickysinclair Nicky Sinclair PGA (@nickysinclair) reported from Windsor, England

    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • 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!

  • 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!

  • PGcomms Peter Gordon (@PGcomms) reported from Guildford, England

    @O2 hi there - my 3G/4G data facility on the phone hasn’t worked for some hours. Mobile phone signal ok. Is there a data prob?

  • 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

  • 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?

  • 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

  • gonnella Pete (@gonnella) reported from Woodley, England

    @O2 frustrating deal with you guys, 6 months of poor service. Now dealing with your networks team, you quite obviously have a coverage issue in my area. Please just let me leave my sim only contract early thanks.

  • 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 🥳🥳🥳

  • 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!!!

  • 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.

  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

  • 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.

  • ollieeden Ollie Eden (@ollieeden) reported from Farnham, England

    @O2 I’ve been a customer for nearly 20 years, but I will be more than prepared to switch if you fund / pay for advertising on #GBNews #DontFundGBNews

  • 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).

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • 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?

  • 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.

  • 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

  • badblokebob Richard Nelson (@badblokebob) reported

    Been with @O2 as long as I've had a phone, but think I'm going to have to finally bite the bullet and switch. Their app/site is such a pain in the arse to use — it's a struggle to even log in, never mind change anything.

  • the_sarge1984 Chris Carter (@the_sarge1984) reported

    @o2 someone needs to do something g about you guys. The app doesn't work, you only communicate on platforms that I dont have, and currently im not getting what I paid for. I have been on o2 since I was 21, im now 41 and this is by far the worst service I have recieved from you!
