    Great customer service @O2. Placed an online order at 6.30pm last night and arrived 4.45pm in Belfast.

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

    @O2 AirPods and 🎅 is looking after them! Again fantastic service.

  • salexander835 Stuart A (@salexander835) reported from Holywood, Northern Ireland

    @O2 I can't get logged into my account through the app or via the Web. Is there an issue?

  • 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.

  • 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

  • AskkeithInfo askkeith.info (@AskkeithInfo) reported from Castlereagh, Northern Ireland

    @O2 Reece in your forestside store was a legend I ran through door cut off from world and all sorted for phone and lap top in 12 mins a credit to public service he’ll be snapped up by someone soon give him a pay rise and pat on back

  • 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.

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

    @o2 is the worst shittiest network I've ever been on in my life

  • 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

  • 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.

  • columcoyle Colum Coyle (@columcoyle) reported from Castlereagh, Northern Ireland

    @angelcosta78 @DPDgroup_news @O2 @AppleSupport I’ve sent a complaint to O2 asking for a refund of the three days I’m missing out on my device plan. They’ve already charged me!

  • 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).

  • 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.

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

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

  • Jay_McB 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 😜

  • EmGymMum Em (@EmGymMum) reported from Belfast, Northern Ireland

    @O2 @KLogan1977 Update: So @O2 asked me to DM details of the issue. I sent it hours ago, yet still no response. I wonder if there is an intention to help or it is an illusion of good customer service. Nor have I got promised call back after 22 hours from the CS phoneline. Not good!!

  • columcoyle Colum Coyle (@columcoyle) reported from Castlereagh, Northern Ireland

    @angelcosta78 @DPDgroup_news @O2 @AppleSupport Just checked and its now saying the same for me! Apparently it takes a full 26 hours to get from Birmingham to Down 🙄

  • 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

  • leannereid1988 leane reid (@leannereid1988) reported from Castlereagh, Northern Ireland

    @O2 in o2 shop in newtownards the 3 fellas in the shop couldn't have bin any nicer and very helpful even when the problem was my own fault! Saved me a trip to Samsung! Def need a pay rise!! Thank you =)

  • Colchesterviews ColchesterViews. (@Colchesterviews) reported

    @O2 Pathetic excuse of a company. The priority was down most of the time. Touts now have them, you’ve let us all down.

  • AdamAKnight Adam Knight (@AdamAKnight) reported

    @O2 The 3 month trial of Uber One on the O2 Priority app says it's already been used, would you be able to help at all?

  • andyfilby andy filby (@andyfilby) reported

    @O2 seriously you have the worst customer service of any of the mobile phone companies. Dm also sent, no reply again 😡🤬

  • AndiMadd Andy Madanat (@AndiMadd) reported

    @LilHay @O2 It is yeah, I think they’re hoping we just give up and go onto live chat or ring O2. They give us false hope that they’ll reply to our query but never do. So much for replying ASAP… “as soon as possible” 😕🫤

  • louiisek1 kelly (@louiisek1) reported

    @o2 on Monday I was assured the order had been cancelled and I would be refunded my deposit. 4 days later no refund and you’ve sent me out the phone I cancelled not the new one I placed after I had cancelled. My new order is on hold because of issues your end and you now want

  • ammmie ★Amy★ (@ammmie) reported

    @O2 can someone help me with how to sign onto an account. I can’t use the help page because I can’t get into app either

  • jordan_lawtonn Jordan Lawton (@jordan_lawtonn) reported

    @ThreeUK @ThreeUKSupport why have rewards and presale if we can’t purchase things or after waiting in a queue for hours to then be kicked out. Poor poor poor. Should’ve gone to @O2 a while ago much better customer service as well as network

  • John_baggies70 John_baggies70 (@John_baggies70) reported

    @KirstyLBx @O2 Peter kay is awful
