    @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

  • 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

    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 🥳🥳🥳

  • 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 👌🏻

  • 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.

  • 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?

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • 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.

  • 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!!!

  • 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!

  • 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.

  • 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

  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • 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..!

  • 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.

  • 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

  • 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.

  • 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

  • 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).

    @O2 hi please could you help, my dad is trying to access myo2 app but it is saying his account hasn't been activated, could you advise best number for him to ring, going round in circles on online help, in his 70s and I don't live with him. Thanks 🙏👍

  • robsmith115 Rob Smith (@robsmith115) reported

    If you are thinking of getting a mobile phone with @O2, take my advice, DON'T. Customer service is appalling. #badcustomerservice #o2

  • join4te Jay (@join4te) reported

    @O2 Day 128 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

  • midlandno4 Karl Jeffries (@midlandno4) reported

    @O2 any chance someone could answer the phone in customer service? Shocking 20 minutes and still waiting

  • AtkinSoares Atkin (@AtkinSoares) reported

    @O2 please help with proof of barring letter! Was to receive it hours ago and nothing yet! It’s urgent and no help from OutOfHours team!

  • Taylod61 ❌ David Taylor 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧❌ (@Taylod61) reported

    Wow @O2 have really excelled themselves today. 4G network crashed by 7.20am. 👏👏👏👏👏👏 No other company could achieve this level of incompetence

  • alex_BRoden Alex Roden 🔰 (@alex_BRoden) reported

    @o2 day 5 and still now network in my area! What is taking so long to resolve this issue?!

  • 3_Heart_S 3Hearts (@3_Heart_S) reported

    @O2 any ideas if there’s a service issue in CM13 area please? I can’t get a signal for voice calls.

  • RobTrav Rob (@RobTrav) reported

    @O2 Hello. I’m in a pickle. So I’ve set my 30days to cancel my account. About 35 days ago Just now I’ve gone to log in to my o2 app said there was an issue so I refreshed it. And changed my password but it requires an authentication code. That sent to your 02 number.Unfortunately

  • CDFJSEC Ciaran D (@CDFJSEC) reported

    @O2 signal work in my area for a week - when you gonna refund me for a lack of service?
