    Samantha G (@SamCamLlamClam) reported from Greenisland, Northern Ireland

    @O2 repeatedly ignored by your dms.. been trying to contact you for days - I am incredibly distressed and humiliated by this treatment. Quick enough to get in contact when you want someone to sign up.. not so much when someone wants to cancel their account. Sort it out.

  • IanRobinson
    Ian Robinson (@IanRobinson) reported from Stormont, Northern Ireland

    @chriswb @O2 No. Plus it says No Service where the O2 logo should be. I might try the SIM in my O2 iPhone.

  • cimota
    Matt Johnston (@cimota) reported from Lisburn, Northern Ireland

    @O2 You don’t get the same experience on @ThreeUK - never get shady third party companies calling. You treat your customers like another product to be sold. It should be criminal. I’m actually disgusted. 🤮

  • jtoal
    James Toal (@jtoal) reported from Belfast, Northern Ireland

    @O2 Yes of course it is, but not when I needed it last night. It is *invariably* down when I try to use it late at night. I raised this issue a few months ago also.

    Jason Brown (@Jay_McB) reported from Newtownabbey, Northern Ireland

    @virginmedia come on I have 4 Sims with VM. Even put something together online. Will @virgin customers be getting any rewards or paybacks like @O2 had to do when they kept getting network problems 😜

  • McGuinnessKevin
    Kevin McGuinness (@McGuinnessKevin) reported from Belfast, Northern Ireland

    @o2 any chance you can sort out the masts in Belfast.. really slow connections and dropped connections, I’m even with o2 (was with you when it was BT Cellnet) I’m with sky who use your network but I know of o2 customers having the same issues. #o2network

    How do I make a complaint with @O2

  • cimota
    Matt Johnston (@cimota) reported from Lisburn, Northern Ireland

    @Aerial_Direct @O2 You play fast and loose with customer records and exploit trust. Shame on @o2 for a blatant breach of customer goodwill.

  • adammccalden
    Adam McCalden (@adammccalden) reported from Belfast, Northern Ireland

    @virginmedia since my virgin mobile UK signal has been shifted from piggyback Vodafone to @O2 it has been a complete disaster, constant signal dropping, constant WiFi calling cutting. This is before my account has been transferred to O2. Complete and utter rubbish

  • roryg2009
    Rory Gallagher (@roryg2009) reported from Belfast, Northern Ireland

    @o2 I resorted to emailing the CEO today @LutzSchueler because no one will help me with refunding me for an order I cancelled and didn't receive...

  • cimota
    Matt Johnston (@cimota) reported from Knockmore, Northern Ireland

    @O2 But thanks for your valiant “how can we help” which you know and I know was “customer service theatre”. 🎭 It really gives the impression you care one iota about customer service and privacy. 👌 Which is, of course, nonsense. But good play 👏

  • catherine271076
    Catherine Dwyer (@catherine271076) reported from Jordanstown, Northern Ireland

    @O2 I need to escalate a complaint re. a member of staff who refuses to to 1) process my upgrade and 2) who has just terminated my call. Who can I talk to? Your staff say it’s not possible to talk to a manager.

  • GeorgeCowan
    Britishgamerni 🇬🇧🏳️‍🌈 (@GeorgeCowan) reported from Newtownards, Northern Ireland

    @O2 Yeah that doesn’t give any way to report an issue or anything not helpful

  • timjacko09
    timjacko09 (@timjacko09) reported from Ballygowan, Northern Ireland

    @O2 I’m having problems sorting out the “extra” that came with my recent upgrade. Today is day 28, I need to choose today. Please help asap!

  • cimota
    Matt Johnston (@cimota) reported from Lisburn, Northern Ireland

    @O2 Which was apparent from my first tweet. I’m not asking for you to intervene. I was asking when are you going to develop some principles and stop selling your customers details to bad players like @Aerial_Direct

  • padraigmc1988
    padraig mc crory (@padraigmc1988) reported from Belfast, Northern Ireland

    Is it just me or has @O2 phone signal went to the absolute dogs?

  • Utter_Dil_Emma
    Mad Madame Em (@Utter_Dil_Emma) reported from Belfast, Northern Ireland

    I assume my bus home crashed and I died because hell is surely dealing with @O2 customer service chat for a ******* hour and a half.

  • Deadandgone70
    Joel Ferguson (@Deadandgone70) reported from Newtownards, Northern Ireland

    Glad I’m leaving @O2. Trying to recycle my phone and according to CEX, TescoMobile and Game the small mark on my phone wouldn’t be a problem. But send my phone off and they say they’d give 50% of the value. Jokers like. Even in store they said it wouldn’t be a problem

    💡 check your Tesco clubcard account - vouchers for restaurants, Denby dining sets & more - I’ve enjoyed 3 course meals for 2 for like £1.13! 💡 check your topcashback account could be £££ for a M&S voucher for example 💡 If @O2 customer make sure you download free priority app

  • internetsense
    Philip I Wilson (@internetsense) reported from Belfast, Northern Ireland

    @LauraJ2803 @SarahSherry1 @O2 This is criminal activity I was charged £2 per day by #Three Which is bad enough Truth is like petrol/oil/electric/tv you can't change as they're all at it!

    @arokorol @O2 Your network carrier is at fault.

  • nathan1harrison
    Nathan Harrison (@nathan1harrison) reported

    @O2 been with for years and this past few weeks your single has been awful, can’t access apps that I need to park, charge the car, really isn’t great service, you say you have teamed up with starlink, honestly you whole system is terrible, think I might be moving providers

  • gagancheetu
    gagan cheetu (@gagancheetu) reported

    @o2de My contract was cancelled about a year ago and a refund was confirmed. However, I only keep receiving monthly credit notes by email, but no money has been transferred to my bank account. Please urgently check and clarify. Customer no.: 6094099929 @O2

  • danielbrady82
    Daniel Brady (@danielbrady82) reported

    Really need to commit to leaving @O2 when my contract expires. Those Artemis astronauts had better signal than what I seem to get. 4 bars, 5G and **** all. We pay more and more, but get less and less.

  • colbridgey
    emily (@colbridgey) reported

    @Ticketmaster @AXS_UK @o2 you need to sort this out immediately. I can’t buy one single accessible ticket so it adds my carer ticket automatically. Then it says I can’t buy these tickets because of the spare seat. And it won’t even let me purchase the spare seat?? So I can’t buy the damn accessibility tickets

  • asahmed59
    AA (@asahmed59) reported

    @arokorol @O2 Its just wherever phone picks up signal from a tower and whoever uses that tower. Its not that deep. Go find a tiny violin

  • MishehooA
    Misha Hoo (@MishehooA) reported

    @arokorol @O2 Receiving a "Welcome to Palestinian Authority" message at Ben Gurion Airport happens bc your phone connects to the strongest available signal, which can sometimes be a Palestinian network tower located in the nearby West Bank, rather than an Israeli one. NothiNothing malicious.

  • DanJones2012
    Dan Jones (@DanJones2012) reported

    @O2 He’s just sent me an email saying his phones not working properly now, said all the writing has turned into a different language, have you cut him off?

  • frannyporter
    Fran (@frannyporter) reported

    @O2 @dermothill11 Can't he's got no signal

  • 1934rabbit
    wayne daly (@1934rabbit) reported

    @O2 why do I waste my time. Being loyal to a network that I can't trust to work when I need it... Been having this problem for years.. complain a couple of years ago and got feed some BS from your customer service team.. just not good enough... Obviously loyalty means nothing 😡
