  • 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!!!

  • 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?

  • hedaramusic hedara (@hedaramusic) reported from Hammersmith, England

    @O2 absolute JOKE of a service today. Got a deal offered to me by your retentions team TODAY, I ring back later to call it and no one with authorise it. Been passed to and fro for an hour and a half and got NOWHERE. The phone and deal I want is sat in my basket. 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.

  • Si11y3gg Pawlie (@Si11y3gg) reported from Richmond, England

    @VixSeaman @EE @O2 I’m with o2 also! Was with Three before, but would never bother with EE. I will only do sim only.

  • 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.

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before - I’ve now tested on both front and rear cameras with and without HDR and it bleaches every time. Is the product faulty @AppleSupport or is this an iPhone 12 issue in general. How can I fix it?

  • depeare Steve Depeare (@depeare) reported from Ealing, England

    @O2 I’ve tried desperately trying to get hold of customer service and keep getting knocked off. I need a 5 g SIM card for my new iPhone 12 pro plus and need a 5 g sim , I think a card may be ordered but not the 5 g

  • Katie_Lewis_ 𝕂𝕒𝕥𝕚𝕖 (@Katie_Lewis_) reported from Kingston upon Thames, England

    @TweetFlicker @O2 I know, o2 used to always be the best now its gone down hill fast! Sky mobile is brilliant, my daughter is on it and you get good rewards with it like o2 moments, but better!

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • 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

  • AndrewCarrier Andrew Carrier 🍸 (@AndrewCarrier) reported from Hammersmith, England

    @cgledhill @McDonaldsUK @O2 I think the more pressing question is: Why are you using a public wi-fi network?

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

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

  • 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!

  • 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

  • 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

  • VictorJ1987 Vìncere. (@VictorJ1987) reported from Brentford, England

    Thanks @VodafoneUK for the run of 3 poor months of customer service requiring us to request for cancellation. Typical that your retention team could not even be bothered to make an effort. Go and listen to the phone call. I guess @EE or @O2 here I come. #Vodafone #Dontbother

    Two days ago I had an error message on my phone saying "SIM not provisioned for voice" and now all I have is "Emergency Calls Only" I cant send or receive voice calls or text messages on my phone how do I resolve this @O2 ?

  • LydiaGerman1 Lydia German (@LydiaGerman1) reported

    @O2 are you having issues with transferring numbers at the moment? I started a contract with you on Tuesday and gave you my PAC number, it hasn't been transferred yet

  • sailortowntour SailortownTour (@sailortowntour) reported

    Just had one of my worst customer experience in years instore @O2 in Islington. Thankfully out of contract and was intending to renew but not after that level of incompetence, inability to comprehend, refusal to find solutions and contemptible attitude. Piss poor.

  • sharkbait_____ M A R I A N N E 🌻🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@sharkbait_____) reported

    @O2 Hi Team. I am looking to terminate my contract after the email this morning around changes to T&C's which I am entitled to do. I have been told however I cannot keep my number if I terminate early? Please can you advise?

  • Langtrams lawrie thomson (@Langtrams) reported

    @O2 I'll be glad to leave O2 as not only is there service crap but there customer service is even worse

  • putanginomoe Benzel Washington (@putanginomoe) reported

    @O2 financial hardship is no joke and the stress im under is ridiculous but yet all I get told by your stupid "ai" bot is to go to the contact us page where I'm told to ring or write which I can't do

  • TEEE_man TeeManTV (@TEEE_man) reported

    So @O2 have an ‘outbound’ team who call you to give you an offer which initially wasn’t possible. Only problem is, you can’t call this team back to redeem their offer because they dont accept inbound calls?? What is actually going on here?

  • psschoe Psschoe (@psschoe) reported

    @O2 why is your 4g network now unusable only 5g works properly when I go out of 5g coverage phone data basically stops working very annoying

  • joannahalina Joanna (@joannahalina) reported

    @O2 is genuinely the worst company I’ve ever that displeasure being a customer of 😩 the way they mess simple things up is on a whole another level 👎🏻 #facts #Disgraceful

  • GaryJones1965ti Gary Jones (@GaryJones1965ti) reported

    @O2 Can I make all O2 Customers aware that the free Disney offer will revert to a charged service unless you cancel this extra 😡
