    @O2 Hi my gran is an elderly customer of 02 and keeps getting calls from 02 and has said many times not to ring her again and you keep doing so I want an explanation !

  • 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 🙄

  • 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.

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

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

  • 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 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!

  • 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 😜

  • 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

  • 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.

  • mcadam_rob Rob McAdam (@mcadam_rob) reported from Lurgan, Northern Ireland

    @coolfm just when you feel it could be you winning the cool cash call , the stupid networks @tescomobile & @O2 are down and have been for over an hour now 😠

  • 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

  • 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

  • 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).

  • Kyle87550379 Kyle (@Kyle87550379) reported

    @O2 @Kevin_H84 Rubbish o2, all foreigners at call centre, useless and even ceo mark Evans lazy useless, I've had service cut and £100 go missing in payments, complaints ignored disgusting company don't go with o2 at all

  • IamAndreSousa André Sousa (@IamAndreSousa) reported

    @O2 Still unresolved, and haven't heard anything back from your customer service.

  • ILPadrino1994 Mark Padden (@ILPadrino1994) reported

    Well after a week of twitter only half working, apps not loading on WiFi. After resetting every possible thing on my phone & the router for it to still not work. After buying a new phone from @O2 and finding the problem was still happening. After finding last minute that...

  • lnksav LalaK (@lnksav) reported

    @O2 just checked your network issue page on your site and says a mast is down in Basingstoke. Any updates if this is being fixed? Frustrating not being able to text/call/use the internet! Will there be any compensation as its been at least several hours?

  • devon000001 tyeler4 (@devon000001) reported

    @O2 I need to cancel my contract with you but as usual I have no signal to call ? Can this be done online ?

  • janeyb007 Jane Vaughan (@janeyb007) reported

    @O2 absolutely shocking service from your adviser today who was so unhelpful. My dad has lost his phone in hospital, unable to call and you refuse to send a new SIM to his home address but are quite happy to continue taking payment! He is now completely isolated. Thank you!!!

  • m1ss_muffintop Mrs Paget ♥️ (@m1ss_muffintop) reported

    Is anyone else having issues with @O2 setting up second direct debits for unlimited amounts, in different company names without informing you? Absolutely useless and zero customer services. Won't be staying past the 12 month mark.

  • wood2307 woody2307 (@wood2307) reported

    @O2 My wife has a technical issue with her phone (everything coming up no caller id). Live chat is useless with no reply for days. Just need a resolution. This stuff shouldn’t take weeks..

  • Ccullen834 Caoimhe Cullen (@Ccullen834) reported

    @O2 I have again, for the FIFTH month been charged incorrectly. After speaking to five people, five times being told that the issue would be resolved by my next bill!? Who can I speak to about this

  • Doug_Paulley Doug Paulley (@Doug_Paulley) reported from York, England

    @BNewtonUK @LloydsBank @O2 Thank you. I thought it was dodgy as all ****. Also, presumably they archive their WhatsApp chats. I do. So anybody at their company, with the WhatsApp login, have access to my full card details. Maybe i should change my card
