    @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!

  • 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

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

  • 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

  • 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!

  • 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).

  • ollieeden Ollie Eden (@ollieeden) reported from Farnham, England

    @O2 I’ve been a customer for nearly 20 years, but I will be more than prepared to switch if you fund / pay for advertising on #GBNews #DontFundGBNews

  • aamer74 aamer habib (@aamer74) reported from Maidenhead, England

    @O2 @England My ba p2 priority codes for the cinema are not working

  • 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

  • gonnella Pete (@gonnella) reported from Woodley, England

    @O2 frustrating deal with you guys, 6 months of poor service. Now dealing with your networks team, you quite obviously have a coverage issue in my area. Please just let me leave my sim only contract early thanks.

  • 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 🥳🥳🥳

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

  • PGcomms Peter Gordon (@PGcomms) reported from Guildford, England

    @O2 hi there - my 3G/4G data facility on the phone hasn’t worked for some hours. Mobile phone signal ok. Is there a data prob?

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • 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..!

  • 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.

  • WayneHanley Wayne Hanley (@WayneHanley) reported

    WTAF @O2 your call centre just literally put the phone down on me when I asked for my money back for the 2 months you have billed after having moved to a different provider 3 months ago! Utterly appalled #badcustomerservice

  • CatFankles Gem (@CatFankles) reported

    @O2 @BobPlumb7 Lol I love how you respond to this customer (I feel his pain, O2 is awful so far for me too) even though my message was sent much earlier. Still no response from you and I've still got no service...

  • Vicki_Scotty Vicki (@Vicki_Scotty) reported

    @davmcj @O2 You’ll see loads of us with the same issue and O2 seemingly don’t care. Spoke to someone today after being ignored on here and got told it’d be done by 6pm today. Nearly half 9 and still no switch over.

  • RogSaxton rog saxton (@RogSaxton) reported

    @O2 been waiting 5 days for you to transfer my number to your SIM card. can't get thru to your customer services.

  • famelicose2 famelicose (@famelicose2) reported

    @O2 Hi - Another problem sadly. When I upgraded my SIM only to 25GB per month, I specifically asked the person I was chatting with whether it meant I could roam freely up to the 25GB and was told YES! 1/n

  • CatFankles Gem (@CatFankles) reported

    @O2 the best bit is I didn't even request my old number to port today & was told you didn't have a port request on record, so I was holding off on porting (mainly because of your shambolic service so far). Then late last night I randomly got a text saying you're porting it today!

  • barclay1988 Scott 🇺🇦 (@barclay1988) reported

    Absolutely disgusting customer service from @O2. Avoid them at all costs. I will be leaving at the earliest opportunity. So bloody frustrating. #LeaveO2

  • fbateallthepies Dowsey (@fbateallthepies) reported

    @O2 I’ve just been on the phone 4 32mins 2 try & pay my bill, I finally got through 2b told .. we r now closed & there is nothing he could do .. then the person on the phone deliberately started 2 say that I was being rude & when I asked 4 his name,he put the phone down #disgrace

  • rondon Ron Donaldson - Narrative Ecologist (@rondon) reported

    @O2 I have waited 2 days for switch of old number to new O2 SIM and now I am getting "SIM 1 not provisioned" error. I cannot now ring customer services and chat lines say not available. Can you help me please?

  • BobPlumb7 **** Burger,🏴󠁧󠁢󠁥󠁮󠁧󠁿🇺🇲 100% #BackBoris (@BobPlumb7) reported

    @O2 1st operator said go to store 0 help, 2nd operator never noticed my acct was not active so the number swap the operator arranged got cancelled, 3rd operator sorted my acct but not transfer of old number from 3, total time spent on 3 calls and 1 shop visit = maybe 5-6 hrs
