    @Ali_Malik @O2 @Ofcom @MarkEvansO2 @markevenso2 giving us a day of refund not helps actually! Some of us are running full businesses on your network.

  • OmarMansoor Omar Mansoor (@OmarMansoor) reported from London Colney, England

    @Ali_Malik @O2 @Ofcom @MarkEvansO2 I’ll give them a #Valentine chance - never had issues before but now only on crucial days they go down. #

  • davidweir1973 davidweir (@davidweir1973) reported from Ilford, England

    DO NOT USE @O2 **** SERVICE!!!!!

  • iLloyd_Sa لويد سا (@iLloyd_Sa) reported from Brentford, England

    @o2 can you fix your network in Westfield as I’ve tried to FaceTime my mom more than 50 times the calls have been dropping all the time its sucks paying almost £90/Month and you don’t get basic network coverage inside the mall. Not a happy customer anymore.

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 #o2guru said they are doing a network investigation for me. It makes no sense to use 1GB of data in 53 minutes whilst at the theatre. I’d have to be live streaming for that to happen! #o2 @TheO2 #1gbdata #goinggone

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 and if you are on call your call will be dropped(call failed)then it will take sometime fr service to start working again.. 2ndly most of the places getting only 1bar and very slow data browsing.. 3rdly when it connects to 3G it’s same like No Service it goes sooooooo slow 2/2

  • iLloyd_Sa لويد سا (@iLloyd_Sa) reported from Hammersmith, England

    @o2 can you fix your network in @westfeild #London as I’ve tried to FaceTime my mom more than 50 times the calls have been dropping all the time its sucks paying almost £90 pcm and you don’t get basic networks. Not a happy customer anymore.

  • chloefinlayson Chloe Finlayson (@chloefinlayson) reported from City of London, England

    @naomihall_ @O2 It’s so frustrating! When I checked yesterday it said service was fine in Islington but then when I got home had to data there either 😥 glad it isn’t just me having issues though

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 i have few screen shots of different areas when it’s service just disappears, call failed and only 1 bar, will share screen shots with @O2 3/3

  • sophiegdonnelly Sophie Donnelly (@sophiegdonnelly) reported from City of London, England

    @O2 please can you do me a favour and dm me so I can give you my friend at works number to call her back - she has some questions about her phone contract and nobody on your customer care line seems to know the answers - don’t make me listen to her ranting anymore pls 😢😢😢😢😢

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 remember few months back when @o2 was down for nearly 2 days.. after that it’s service is going down everyday.. sometime when you are travelling and passing from certain areas O2 service will simply shift to 3G form 4g and sometime it will be No Serive at all 1/2

  • iLloyd_Sa لويد سا (@iLloyd_Sa) reported from Hillingdon, England

    @O2 It’s doesn’t help!!!!! It’s getting frustrating day by day been with @02 nearly 7 years and it’s getting worst day by day. No proper coverage. There’re much better network providers in the U.K. that provide better network and customer services it’s time to make a change!!!!!!!

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    every single day your service going down ,moved to O2 from 3 , paying more getting less as compare to 3 but your service is kind of same , most of the places it just disappears, call failed, hardly one bar most of the time and no service at certain places.. v disappointing @O2

  • Ali_Malik Ali Malik (@Ali_Malik) reported from London, England

    The ordeal continues. @O2 and it’s #CustomerService is very good at taking notes but appalling at resolving complaints / closing issues. Generated an incorrect / inflated bill despite multiple assurances otherwise! Now running pillar to post, no resolution in sight @MarkEvansO2

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 I tried. I think you guys list connection. The guru went to check and never came back!!! 🙈😩 @o2 #o2guru

  • NeilNutbeam Neil Nutbeam (@NeilNutbeam) reported from Hillingdon, England

    @O2 why is the network and 4g soooooo bad. Well I say 4g, I never get 4g most of the time. And even if it does say 4g it’s rubbish and slow, stuff still doesn’t load. A lot of the time I have to turn 4g off and change it to 3G for it to work. Rubbish

  • JamesSu30049584 James Sullivan (@JamesSu30049584) reported

    @dhlexpressuk @O2 31406664521217 Hi I keep chasing with O2 and your company keep saying to call back. I'm being told it's being investigated. Your tracker shows the driver never parked outside my house and all my neighbour's cameras didn't see the driver either

  • Andy_Watt Andy Watt (@Andy_Watt) reported

    Interesting customer retention policy from @o2. Rang about the price rise and they offered me a more expensive plan with more data (don't even use what I currently have). Cancelled both Sims after that. #o2priceincrease

  • ian_hindy Ian Hindmarch (@ian_hindy) reported

    @O2 17.3% increase in price in April 2023 following 11.7% April 2022 is absolutely disgusting! Two increases during one contract term taking a £36 bill to over £47. It wouldn't be so bad but the coverage is terrible and Internet speeds slowest of all the networks. #getinthebin

  • SJNC90 SC (@SJNC90) reported

    Hi @O2 , do you genuinely think a 17.3% bill increase from April is fair or reasonable? Or do you just want to be honest and say you're money grabbing thieves and taking advantage of a situation? I'm not sure why I've bothered to be a customer for the best part of 18 years.

  • blackrebelpete Pete Owen (@blackrebelpete) reported

    @garyker @O2 @Ofcom This is disgusting. Already over priced. Tied into Virgin contract and terrible coverage.

  • ScubaJeff904 ScubaJeff (@ScubaJeff904) reported

    @O2 3 days and no support, tried on here, ringing O2 only to have call terminated, and DMs on here.... I give up, I'm cancelling my direct debit then when you try and contact me, I'll ignore you like you're ignoring me.

  • gi38928705 Gil (@gi38928705) reported

    @O2 #O2 @TheO2 @O2 highly unprofessional and poor customer services - iPhone with non genuine camera !!! O2 doesn’t seem to care ….where as I paid hefty amount to get genuine phone … Apple also confirmed “Phone failed camera’s authentication” but nothing done by O2

  • realMattToomer Matt Toomer (@realMattToomer) reported

    There is currently a 45 minute wait on the @O2 Customer Service numbers, I can only presume that everybody is phoning up to cancel giving that O2 are increasing prices by 17%.

  • julierawlings julie (@julierawlings) reported

    @O2 you keep cutting me off 5 times so far. my bill has gone up again on a sim i dont use because @virginmedia told me i had to take it out with my package. I just want to know how long I have left so i can cancel it.

  • HHBarn garDan (@HHBarn) reported from Rawtenstall, England

    @O2 how can we have no mobile or 4g/5g service till Thursday.. Seriously is this a joke..
