    @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!

  • 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.

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

    How do I make a complaint with @O2

  • 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.

  • 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 =)

  • 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

  • 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

  • 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 !!!

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

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

  • 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 😜

  • 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.

  • 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

  • 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 👏

  • 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 🙄

  • 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

  • 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!!

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

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

  • 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

    @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.

    @O2 2/2 from the o2 shop in Durham, he couldn't have been more helpful and did go over and above to help me this morning!

  • SANKALP4664 SANKALP SHIRODKAR (@SANKALP4664) reported

    @O2 is one of the worst service providers having been on the line for past 2hrs and they yet could not solve my problem

  • JamRuler89 James (@JamRuler89) reported

    @O2 Barely getting 3G while my wife is getting 5G on another network. Why can’t O2 improve in Lanarkshire?

  • LexOtter Lex (@LexOtter) reported

    @O2 Had no service for over a week now in my area due to you working on a mobile service tower, why am I paying for a service while I can't use it this is mad

  • ajameson1008 Amy Jameson (@ajameson1008) reported

    @kellyja90235455 @O2 Me too! Two contracts taken out fraudulently and can’t speak to customer services unless I pay the fraudulent account! Seems to have happened to lots. I’ve never been an o2 customer! So stressful

  • Gus_765 Liam Smith (@Gus_765) reported

    @O2 hello, I’m trying to take out the offer for Disney plus for £5.99 however it’s coming up with an error and then when I click extras, it’s saying that it’s £7.99. Can you help?

  • AmieBirkett94 Amie Birkett (@AmieBirkett94) reported

    @O2 are the shittest phone network with the WORST customer service ever. A loyal customer for over 10 years and I have had the same issue going on for over 5 months!!!

  • PokerDaz9 Daren Taylor (@PokerDaz9) reported from Radipole, England

    The @O2 network has to be the worst ever. Even with a strong 4G signal, you still can’t get any data use!!! Certainly over subscribed. #notfitforpurpose #OFCOM

  • 6thGrom Grom McGromface The 6th (@6thGrom) reported

    @O2 Apologies. With the fold you don’t offer loss or theft. Only accidental damage

  • David_C66 David Clark (@David_C66) reported

    @O2 I think I've sorted it. It's taken a few attempts, although the promised a confirmation email that I've been promised every time I've attempted to cancel, has never arrived.
