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

  • apallan ANN P V ALLAN (@apallan) reported from Belfast, Northern Ireland

    @Girlzmum Very poor service from @O2 especially to a front line worker in the NHS #NHS who needs her phone.

  • BrendanB2 Brendan Bonner (@BrendanB2) reported from Belfast, Northern Ireland

    @O2 I wouldn’t recommend anyone buying online and redeeming your phone. Go to the store, you can’t trust any of the online and virtual services. Was a handling getting phone set up, getting help and they only give you 50% of the value they say (no matter how good your phone is).

  • UberGeekFanboy Fanboy (@UberGeekFanboy) reported from Belfast, Northern Ireland

    @O2 trying to phone through to return a phone and keep getting cut off? Wtf.

  • RunRosyRyanRun Bacon From Heaven (@RunRosyRyanRun) reported from Belfast, Northern Ireland

    @O2 I won an instant prize from Greggs but no voucher appeared, can you help?

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Belfast, Northern Ireland

    @O2 you guys got a number to your payments team? I need to speak to someone. Automated IVR is poor.

  • thebaldfather Hugh Pollock (@thebaldfather) reported from Belfast, Northern Ireland

    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

  • 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.

  • JeremyAdamsNI Jeremy Adams (@JeremyAdamsNI) reported from Belfast, Northern Ireland

    Kudos to @O2 for customer service today. Recommend going via app ‘Start a Conversation’ section.

  • kkanecelt kierankane (@kkanecelt) reported from Belfast, Northern Ireland

  • Watsonmydear Christine #StaySafe #SaveLives Watson 💙 (@Watsonmydear) reported from Belfast, Northern Ireland

    💡 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

  • 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.

  • GarethAJMiller Gareth (@GarethAJMiller) reported from Belfast, Northern Ireland

    @EmmandJDeSouza Burnfoot, Donegal house in Derry UK Workshop Donegal, Irl @O2 flicking from roaming to home constantly, useless turning it off roaming I'd never get any work done👿

  • 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

  • billyjatkins billy (@billyjatkins) reported from Belfast, Northern Ireland

    @seanp280 @O2 Where are you in Belfast? I live beside city hospital and I get full bars all over the city, 5G too! Only when I venture into the depths of County Down does it deteriorate lol

  • 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...

    @Lisa40152958 @O2 Have you had your issue resolved? This happened to me the other day with #o2 & apparently it’s been reported to the fraud department. They said it could take up to 30 days to hear anything but today received more letters saying i still owe money. So suspicious.

  • Nintyworldchamp Nintyworldchamp (CPS/AIC) (@Nintyworldchamp) reported

    @thelifeofjadey @O2 That's terrible 🤬

  • nicurro Nigel Curtis (@nicurro) reported

    @O2 are you actually taking the p*** out of mobile phone customers in Armthorpe, Doncaster ? Signal problems with 4g for over 2 years now, 3G available but useless and then you start trying to introduce 5g. #useless

  • AnthraXFPS AnthraXFPS (@AnthraXFPS) reported

    @virginmedia @ITVChase @O2 You lot are complete rubbish! You are fast enough charging extortionate amounts for your packages, an prices keep rising, zero discounts to old loyal customers! Yet you still seem unable to keep internet stability a priority, and your call centres are a joke.

  • ms_arsenal1988 danielle richards (@ms_arsenal1988) reported

    @nicurro @O2 Virgin have teamed up with o2 now so I’ve really noticed the difference virgin don’t get me wrong have other issues but I really identify the difference…I was with o2 from the age of 16 till maybe 6/7 years ago and the service back then was amazing and coverage now terrible

  • McMajular McDazzle83 (@McMajular) reported

    @virginmedia @ITVChase @O2 Down in the Birmingham area. Not only am I using my data now,but my helium hotspots not earning either!

  • bellenes_peter Peter Bellenes (@bellenes_peter) reported

    @O2 just switched to BT and receive threatening "Enforcement Letter" - this is the first letter and direct debit still in place. Not a good invitation ever to return. As my granddaughter said "Never going with them"..

  • Vijay_781 ᐯIᒍᗩY ☬ (@Vijay_781) reported

    @O2 Hi, my number ported over from EE on Monday but today I noticed text messages fail to send and in settings > phone > my number it shows the number that the O2 SIM originally came with, it doesn’t set when I try change it. In the myo2 app the number shown there is fine.
