  • 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!!

  • 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

  • salexander835 Stuart A (@salexander835) reported from Holywood, 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.

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

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

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

  • 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!

  • 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.

  • 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

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

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

  • StephenScarth Stephen Scarth (@StephenScarth) reported from Bangor, Northern Ireland

    @O2 Hi having problems making and receiving phone calls on a IPhone SE #O2

  • 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.

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

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

  • 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 =)

  • 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.

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

  • 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).

Latest outage, problems and issue reports in social media:

  • CorbettAndy andrew corbett (@CorbettAndy) reported

    @O2 a week ago I reported that we have no signal in the area. So far you’ve established I didn’t know I had a password for my account. Please fix the damn transmitter mast.

  • Adi770839136 Adi7 (@Adi770839136) reported

    @O2 @LutzSchueler So the policy is still to play dumb? What happened is that O2 co-developed a payment system that was exploitable by scammers. Customers had money stolen directly from their accounts and O2 refused to help.

  • DianeKemp1 Professor Diane Kemp (@DianeKemp1) reported

    .@O2 how do you get an answer from your fraud team when 1 No reply in 28 days, yet 2 Your customer service says they’re dealing with it.

  • JanieNoir Janie (@JanieNoir) reported

    @O2 I was about to use my cinema voucher but it’s disappeared from the app and says ‘used’. I didn’t copy it down but was looking to see which film to go to. Please could you help?

  • stacey_b_14 stacey (@stacey_b_14) reported

    @O2 Ohhh no @o2 still not working. Just cuts off snd says 'call ended'

  • chloeewhitexo chlo💫 (@chloeewhitexo) reported

    @O2 hi was wondering if you could track my order or at least see what’s happening with my order - I’m a new O2 customer and ordered a phone/contract on 31st Jan and haven’t had any updates since then except the official documents

  • jadealmann Jade Mann (@jadealmann) reported

    @O2 All credit checks are completed by the network rather than ourselves. They consider a number of different factors and take these all into account when running the credit check. Unfortunately, we are therefore unable to provide any specific reasons. Their reply?

  • Adi770839136 Adi7 (@Adi770839136) reported

    @Payforit_Sucks @O2 @Welly1906 O2 has demonstrated an astonishing cowardice and lack of ethics with regards to Payforit scams. At the end of the day, victims' money was taken from their bank accounts by the network. What they did with it after that is irrelevant.

  • rhianneleighx rhianne (@rhianneleighx) reported

    @annataft_ @O2 Wtf !!! Why so much!!! What a joke! Get moved onto Vodafone, I changed to them from EE and wouldn’t go anywhere else now!

  • Tarunsr1993 TarunSuresh (@Tarunsr1993) reported

    Hi @O2 I've been trying to contact regarding screen replacement but no one has responded till now. Online chat shows all our agent are busy. I'm totally disappointed with your service. Thanks.
