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

  • 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

  • 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!

  • 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

  • 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?

  • 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

  • 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!

  • 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..!

  • 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.

  • 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!

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

    @O2 I rang 202 and they said there was nothing they could do for me, just to change my password Will text that number now, thanks for your help 👌🏻

  • 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).

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

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • 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

  • 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

  • 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 🥳🥳🥳

  • 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.

    @O2 hi got new phone today , transferred everything over , all working fine , only thing it is says no network , tried putting sim back in and reset network setting

  • Ozzy6196 Ozzy (@Ozzy6196) reported

    @SteveBakerHW Terrible, absolutely no difference on @O2 whatsoever. I can have 5G and full signal and have to wait for a webpage to load up, or over a minute or two for an app

  • HistorianJen Dr Jennifer Evans (@HistorianJen) reported

    @O2 how usual is it for your fraud team to overrun their 10-day response time. My mum is very stressed and keeps being fobbed off while receiving more and more demands letter for a contract she never took out. Now approaching 20 days with no decent response

  • ellenfrann Fran (@ellenfrann) reported

    @O2 came off the phone to my friend who’s had a meltdown because of poor customer service. She’s had no service for 10 days, tried to call 6 times, one call attempt took 2 hours, and been hung up on twice 😣 she’s so disappointed. Please help resolve this

  • Jon_oh_oh_7 Jonathan (@Jon_oh_oh_7) reported

    @O2 hi if a select my free gift for being a volt cust, after the free period do the charges for that service come out of my o2 acc or the respective service provider? Im thinking of disney+ or amazon unl music, thanks

  • kayteepook Katie Pook ♔ (@kayteepook) reported

    @O2 hi my phone has been playing up since i paid my bill. Services were turned off but since switched back on its been intermittent help???

  • EMMA_JCAMPBELL EC (@EMMA_JCAMPBELL) reported

    @O2 @ODEONCinemas I am always having issues with @O2PriorityUK cinema codes.. hope you can fix this pronto.

  • ThomasScorer Thomas Scorer (@ThomasScorer) reported

    @BorisJohnson @virginmedia @O2 Taking credit for somebody else fixing a problem that you created. Unbelievable.

  • boy_hatch micheal hatch (@boy_hatch) reported

    @O2 She has been all day long and is being told lots of different things, I just find it quite contradicting when it says a 3 month contract but are told to wait longer then that, also I’ve been facing issue myself on my own contract and nobody has come back to me either?!?

  • martin77sc Martin◼️◻️◼️◻️ (@martin77sc) reported

    @O2 are absolutely shocking Haven’t replied to my complaint since 5/1 and yesterday was the 21 day “deadline” to reply to Equifax. That didn’t happen either. Causing me more problems as an ex customer than for the many years (since iPhone 3G) I was with them Never going back.
