    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • 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

    @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

  • 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

  • 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!

  • 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 👌🏻

  • 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

  • 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!!!

  • 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.

  • 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 🥳🥳🥳

  • 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..!

  • 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

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Hounslow, England

    @O2 your signal in Hammersmith is a joke. London in 2021 and can’t even make a phone call.

  • 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.

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

    Poor network in Se6 @O2

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

  • 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.

  • 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 Please help as my SIM card has been deactivated and I keep going round in circles to find a number to contact you on… it’s a pay as you go Thank you x

  • thesentnurse Adenike Olakunle (The Forbes’ Nurse)🇳🇬🇬🇧 (@thesentnurse) reported

    @O2 Yet another disappointment from @O2 again. That refund promise for 17th of May was the 8th promise I’ve gotten from them. Does anyone knows a legal body that protects customer right in the UK? I need to take legal action against @O2

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

    .@O2 network just went from 4G to3G again everyday this crap network fails

  • MFletch87 FLETCH #14 (@MFletch87) reported

    @O2 why does your automated service cut you off when you’re opening times are till 9pm... looking for a new contract

  • Minette_78 Rachel McConnell (@Minette_78) reported

    @O2 I can't see anything on there to help. I'm just going round in endless loops resetting my password then getting kicked out of my account area.

  • lizwebb80 lizellen (@lizwebb80) reported

    @O2 @SkyUK so ive been a #skymobile customer since the beginning of May only to see that a mast is down in my area. No one can hear me on the phone and the updates keep making the date for fix longer and longer. Wish I'd stayed with Vodafone (and that's saying something)

  • Tamzinpatterson Tamzin Patterson (@Tamzinpatterson) reported

    @O2 I don't have another network sim I could test in it no. I've already requested to have my old phone unlocked but I was told you can't unlock it as it's not an o2 device?

  • InFluxSince83 Everything Reflects the Darkness (@InFluxSince83) reported

    Hi @O2 anything you can do to help get these muppets off my back please? Yo what's up with the scammers all of a sudden?! Yesterday had 3 automated National Crime Agency calls, and another one just now. 07545907171 07545907482 07545907892 07545907596
