  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • Marcus_dd1 Marcus (@Marcus_dd1) reported from Southall, England

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • KellyMSanders kelly marie sanders (@KellyMSanders) reported from Bracknell, England

    @O2 hi I waited until the pro max was saying next day delivery to order - it says it right now so I paid my last phone off to order it and ten mins later got an out of stock email. Can you tell me how to cancel everything I just did please?

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • timnisbet tim nisbet (@timnisbet) reported from Hazlemere, England

    I tell you this country is going to hell in a hand cart I don’t think there is one company who gives a **** about anybody. First it was @British_Airways now @O2 tried for 4 hours to transfer my phone promised a call back and guess what sweet ***** Adam #serviceisdead

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • timnisbet tim nisbet (@timnisbet) reported from Hazlemere, England

    The is very cathartic after 25 years with @O2 I’ve left for @VodafoneGroup the o2 customer care and support is utterly woeful. And having given them so many chances I’ve had enough, so over to you vodaphone can you step up

    @O2 I have no signal at all?

  • transannoyer Transyhumiliator (@transannoyer) reported

    @O2 Now that I have left your incompetent service you have left me with an O2 simkit app on my phone that I can't remove. I'm pretty sure this is illegal and will consult my solicitor, meanwhile you can tell me how I can remove it.

  • sgtdusk Callum (@sgtdusk) reported

    Honestly can’t believe how @O2 are carrying on. I was a victim of SIM swap fraud, left with no service for nearly 2 weeks, and told all costs would be covered. Now they’ve got the cheek to text me saying I owe £145 this month. An absolute disgrace. #O2Fail #O2Disgrace #O2Fraud

  • chrismarkhenry Chris Henry (@chrismarkhenry) reported

    @O2 I’ve been waiting on the phone for 15 minutes now to discuss a disconnection. If someone doesn’t pick up the phone in 5 minutes, I’m gone. In a saturated market where client retention is key to your success, your terrible customer service is insane.

  • graemeball GB (@graemeball) reported

    @O2 Not received my PAC code . After holding on for 45 mins . I still did not receive my PAC code. The call centre lied ? Just another scam to keep customer.

  • GinMum ꧁ᴋᴀʀᴇɴ꧂ (@GinMum) reported

    @its_shainotshy @O2 Me too! Both days counted down then straight out of stock! What a scam 😒

  • DeCM__ mads🇵🇸✊🏼 (@DeCM__) reported

    @o2 are *************** with my phone order. How's a customer service agent going to tell me it will be with me by 7th November the latest, we get to the 7th and I've still not had any update. Absolute joke.

  • JRH1865 Justin (@JRH1865) reported

    @StorrPaul @O2 Unfortunately, yes. Signal drops all the time, work recently moved to them as well so can’t even hook up the that. Last time they were any good I had a 3310.

  • PrincessDuggan PrincessLaLa (@PrincessDuggan) reported

    @O2 My Christmas by candle light code is not working please advise

  • Spurschic47 Ann-Marie Thérèse Hopkins 🇺🇦 (@Spurschic47) reported

    Make that 12 minutes @O2 all I keep getting told is to call because you can’t deal with this online anymore! Ridiculous service well it’s not service it’s a joke. I just upgraded my phone with you I’m starting to regret it now
