  • 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.

  • 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 🙄

  • 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 😜

  • 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 👏

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

    @Aerial_Direct @O2 I’ve spoken to Naomi on your team already. That’s was a useless ten minutes. Refused to tell me details of how to cancel - just threatened temrination fees. Offered renewal. Honestly she would have had to have offered a unicorn in a colour of my choice to get a renewal.

  • 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

  • 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.

  • DAVIDBUZZ2904 DAVIDBUZZ2904 (@DAVIDBUZZ2904) reported from Lisburn, Northern Ireland

    @TalkTalk No the @TalkTalk number was 03451720088 And @O2 give me 03451720091 The email number was 03451720032 No success at all very bad customer service so far !!!

  • SWAshleigh Ashleigh Shaw (@SWAshleigh) reported from Ballygowan, Northern Ireland

    How do I make a complaint with @O2

  • 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).

  • 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!!

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

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

  • 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

  • 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!

  • 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

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

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

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

    @O2 2) They’ve endured under this contract for 30 months (exploited by salesmen) and it finally ends in April so they’ve asked me to help them. I went into our local O2 store and they told me it was a 33 month contract, wasn’t actually with them and there would be a termination fee

  • 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 =)

  • johnbee77554498 john bee (@johnbee77554498) reported

    @O2 Can somebody look into the poor 4g in Liverpool city centre around Mann Island. This has been going on for along time now and it always appears to be at the weekend and in the afternoon. Just done a Speedtest and it was 0.24! It’s not just me having issues as well.

  • CarlyxMc Carly (@CarlyxMc) reported

    @racj25 @O2 @Robinwindsor Same here! Been with o2 since 2008 and never received anything except price increases 🙄
