    @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

    Kudos to @O2 for customer service today. Recommend going via app ‘Start a Conversation’ section.

  • 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.

  • 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

  • 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

  • niamharmagh11 Niamh Thornbury (@niamharmagh11) reported from Lurgan, Northern Ireland

    Is anyone else having problems with the 4g on @O2 😭 please tell me my phone not broke

  • 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.

  • 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.

  • abitofmatt Matt (@abitofmatt) reported

    @O2 Hi, I left well over a month ago but have never received a final bill or had any other payments taken. Is it possible to look into this?

  • SimpsonHeather_ Heather Rilling (@SimpsonHeather_) reported

    @O2 absolutely horrendous customer service from you guys today and for the past week to be honest, upgraded with you and still waiting for the phone to arrive, been a whole week now and just had a really rude o2 customer service woman hang up on my husband - what now O2??

  • AdzCrawford2003 Adam Crawford (@AdzCrawford2003) reported

    @aloadobollo1969 @O2 @BlossomsBand You'll probably be asked to take test and there's no issue with that. Vax passports very unlikely as it'll be up to the individual venues and most of them don't agree with it.

  • maryawild05 Maryann Wild (@maryawild05) reported

    Shocking service from @o2. People, please DO NOT BELIEVE that capped bill means they wont charge you. My 9 year old just ran up a bill ,£250 in 3 days.All they could say was oh it’s ok you’ve got till next month to pay it. CAPPED DOES NOT MEAN CAPPED 🤬🤬🤬#shockingservice

  • DGovia Diane Govia (@DGovia) reported

    @O2 Brentcross store. Customer service very rude. I have a voucher to use. Was told store closes at 6.30pm arrived at 6.10pm and shutters were down. The voucher is given to ensure O2 customers visit the store. However customer service was very poor.

  • waldomum waldomum (@waldomum) reported

    @O2 your stores are opening but refusing to let people in if they refuse to sanitize their hands. According to your over zealous employee it's now the law. This is news to me. I have a skin complaint which is highly exacerbated by hand sanitizer. You've lost a 20 year customer.

  • iNemesis__ Dan // Nemesis (@iNemesis__) reported

    @O2 I'm trying to pay my final bill with you guys.. (A whole £1.61).. But it's not allowing me to do so, I no longer have my number on your service, So calling 202 isn't available, I tried the "Landline" number, that didn't work either.. How can I go about paying it?

  • Stuckinlondon1 Stuckinlondon (@Stuckinlondon1) reported

    @O2 my brother says his data is very slow. Is there a reason for this?? I’m the main account holder

  • TheTyChapman Tyler Chapman (@TheTyChapman) reported

    @O2 why is your connection so bad in the Scarborough area! Ive been with you for possibly 10 years, but service is rubbish! Doesnt work in my house unless connected to WI-FI and at work its ultra slow! Temped to move services

  • 0Neji Ben Palmer (@0Neji) reported

    Here's a guide on how not to get an eSim with @O2 SPOILER: Phone mobile network providers are all seriously lacking in customer service.
