  • 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!!!

  • 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

  • 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

  • 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?

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    @O2 Tried everything. (Apart from trying SIM in another phone). Previously if ever ‘SIM not working’ flashed up all I had to do was switch phone on/off. Not this time. 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.

  • 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!

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    My SIM only service with @O2 has packed up inexplicably today; and O2 slow to respond. Anyway I am without phone. So please DM if you need 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

  • 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 🥳🥳🥳

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

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

  • 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).

  • 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!

  • 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

  • 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

  • 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..!

  • 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.

  • 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

    @O2 I raised an email of complaint on 25/12 but I haven't received a reply yet. I understand the holidays but my automatic reply said I'll receive a reply within 5 working days.

  • richieb65288577 richie (@richieb65288577) reported

    @O2 raised a complaint over 5 days ago following numerous calls to a shocking call centre service. Promised a call back from a manager on 29th December within 24hr and nothing since. Been customer for decades and feels like this counts for nothing. Your service used to be good!

  • yilank yilank™ (@yilank) reported

    @O2 Don`t closer look. until november 2021 20 times your colluague said same words. Anyway. No worries. I have names, and even i have records about how rude your colluagues. jesus, How bad company.
