  • 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

    💡 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

    @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...

  • TheRealJackieJ Jackie Johnston (@TheRealJackieJ) reported from Castlereagh, Northern Ireland

    @O2 Thanks. How do we unsubscribe from this ****? We pay for 5 contracts and do not wish to receive these messages particularly on children’s phones.

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

    @O2 is there any way to arrange a call back over Twitter for the fraud team? My mothers been waiting a month now for a call back with her o2 account still locked out, she’s called dozens of times promised call backs and she’s never called she’s still on hold and fraud closes at 6

    @O2 Good Afternoon, I recently tried to upgrade on line via switch up and it wouldnt let me put my Blue Light Discount on and now I can't access it, Can you kindly help.

  • SamCamLlamClam 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.

  • PcConlon P Conlon PC (@PcConlon) reported from Belfast, Northern Ireland

    @DPDgroup_news @O2 your service is a joke

  • flaminflamingo9 Victoria 🇺🇦 🇪🇺 (@flaminflamingo9) reported

    @O2 I'm a loyal O2 customer but your "loyalty" department have been plaguing me with sales calls today! Not good enough! When I ask to be removed from the database the caller just hangs up! #spammysalescalls #dontbeaspammypammy

  • the_sarge1984 Chris Carter (@the_sarge1984) reported

    Why is @O2 so poor in the PR6 area? Both my private and work mobile struggle. And when I say PR6 area, I struggle in alot of the NW of England.

  • NeilPerrins Neil Perrins (@NeilPerrins) reported

    @O2 Hi - one of my PAYG sims has vanished from my o2 account, and won’t connect to the o2 network. Can you help please?

  • poppy2324 Anne 🙂 (@poppy2324) reported

    @SqueakySays @O2 I’ve just signed up for a new broadband contract with BT (carrying on from previous ones) and now am inundated with demands to send my “4G mini hub “ back (haven’t got one, never had one) and no way to tell them that. #notjustO2

  • mccc123bacardi M bacardi (@mccc123bacardi) reported

    @O2 sorry yourselves out my god no network

  • R3_Dead James (@R3_Dead) reported

    Never insure your phone with @O2 what should have been a 3-5 working day turnaround for my phones repair has turned into potentially double that time with no communication with me unless I call them directly

  • gazjsmithy Gareth. (@gazjsmithy) reported

    @Karl_Downey I’m with @O2 Mines showing full signal etc.

  • DrTheaJones Thea Jones (@DrTheaJones) reported

    @O2 been having issues with my phone for months. Keep getting promised calls back from the “back room” in 3 days. No one calls back. Next step will report to the ombudsman and will also be looking at how to cancel my contract and move providers. I have been with @O2 for 14 years

  • the_sarge1984 Chris Carter (@the_sarge1984) reported

    @Cyber_Betty @O2 I have been with them for 15year, and they have just got worse. Most of my conversations get interrupted by being cut off due to signal. Data is slower than a nailed down slug.

  • jonpod1 JW (@jonpod1) reported

    I’m done with @O2 . I live in a capital city (Cardiff) and I can’t even get a signal strong enough to talk on the phone. It says 4G/5G but it’s rubbish. Apparently ‘too many people are using it now’. Not good enough. #O2
