  • 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?

  • 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!

  • 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

  • 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?

  • 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.

  • 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.

  • 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!

  • 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

  • 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!!!

  • 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.

  • 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

  • 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

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

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

  • 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

  • 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?

  • 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?

  • 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.

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

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

  • 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 Cut my grandfathers pay as you go line off hes 88!!! Just spoken to customer support who then cut me off when i asked if she could speak louder...unacceptable

  • Tom1192Molloy Tom Molloy (@Tom1192Molloy) reported

    Ay @VodafoneUK would slap the **** out of you @O2

  • Jessyyy_J Jessica (@Jessyyy_J) reported

    @O2 customer service is absolutely shocking!! Never been so angry in my life!

  • smudgegt Gareth Taylor (@smudgegt) reported

    @O2 My issue is consistently bad, I've done all the usual things to try and resolve the issue but makes no difference at all..I compared my speed with a colleague on another network and their speeds are 10 times faster...

  • NancySampoorna Nancy Sampoorna (@NancySampoorna) reported

    @O2 I got an email about six months free of an Extra and wanted to check from support which extras were available, I’m being told to call the voice support team which doesn’t make sense? Can you help?

  • Evil__Evelyn Evelyn (@Evil__Evelyn) reported

    @O2 You really cannot work out what the problem is? Are you joking. Go look at the screenshots again. If you are that blind then let me spell it out for you. Since the tarriff increase my account says my new monthly payment is 24.57 and yet I paid 24.78 and I bought ZERO extras

  • adamwingie Adam Breen (@adamwingie) reported

    @O2 hi. I just want to let you know your network in Northern Ireland is shockingly bad. The last 3-4 weeks I can barely make voice calls never mind search on the internet when I’m in 4g. Are you doing anything to improve it? My contract renewal is due soon and doubt if I stay

  • michaelcottage Michael Cottage (@michaelcottage) reported

    @O2 also, if not, is there anything I can do to keep my same O2 number but with a new customer contract?

  • albaceltic On the path to Independence SNP (@albaceltic) reported

    @O2 Just wondering how many days it takes to find a Customer Care O2 number, that exists or works, just asking, O2, anyone?

  • LucasJTGleed Lucas (@LucasJTGleed) reported

    @O2 hello 👋🏻 can someone reply to my previous tweets about my Mobile Data issue please!? Getting really frustrated and am considering leaving O2 now…
