  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    @O2 There’s delay then there’s rude. Been 92 working days or 128 days since I complained. @o2 are making it deliberately difficult to contact.

  • fgethearies FGE ⚡️ (@fgethearies) reported from Cardiff, Wales

    Anyone else on @O2 ? My signal keeps cutting in and out 😩

  • TweetterRoss Ross Maisey (@TweetterRoss) reported from Church Village, Wales

    @O2 Struggling with no or little service at home at the moment and it’s becoming very frustrating. I checked the service checker and they comes back as ok. My phone says 1 bar but that doesn’t allow me to use the internet.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    What is the point of complaining to @o2? Complaint sent 06/09 multiple times chased up formally 20/11 no reply now 06/0/21. Told someone looking at as a priority still nothing @MarkEvansO2

  • catlady_cez Cez 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@catlady_cez) reported from Cardiff, Wales

    @O2 hi is there an issue with your network in cf14? Havent been able to get 3g or 4g since yesterday?

  • ImogensMind 👑Immy👑 (@ImogensMind) reported from Blackwood, Wales

    @O2 my friends phone network has completely gone down all day, they can’t call anyone including yourselves. Please suggest what they should do?

  • ChrisEddy_7 Eddy 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@ChrisEddy_7) reported from Cardiff, Wales

    It’s come to something when you can get 4 bars of 4G signal walking between Benidorm and Albir in Spain but can’t even get 3 bars of 3G signal in Cwmbran South Wales 👀 @o2

  • BristolOli Bristol Oli (@BristolOli) reported from Cardiff, Wales

    @BS3Rob @O2 @WBA Been horrendous for weeks - Can’t complete a call without having to call back numerous times - BS3 probably the worst of them all but M4 corridor from Cardiff to Bristol is a close second

  • JaeyKelly Jay Kelly (@JaeyKelly) reported from Bridgend, Wales

    @O2 Are there any networks issues in South Wales? For the past week or so my phone signal reverts to 3G.

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    This weather properly has me over a barrel. Mistreatment by @O2 properly has me feeling down. My #CovidVaccine pain is bad. Some days the demons are just too much to battle...but today is not one of those days. Rest, relax, refocus. #MentalHealthMatters #BipolarDisorder

  • DennerSusan susan denner (@DennerSusan) reported from Cardiff, Wales

    @O2 Customer service shocking! No service on phone since 24th May, SIX calls made to your call centre to resolve issue - now being told to wait for

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (1/3) Sad to say that @O2 are now trying to charge me for a service never used, when I cancelled a mis-sold contract within the 14-day cooling-off period. Almost two months later they're now saying they're going to charge me a late payment fee, plus the bill...

  • dilligaf2k10 BearWith 🐻 (@dilligaf2k10) reported

    @o2 why is your connection on 4G so crap in Brighton & Hove?

  • spandinko sandy (@spandinko) reported

    @O2 It seems to be happening all the time especially when I'm at home. My signal is indicating 4g and full signal yet my Internet speed is under 1mbps. The network guide says there is nothing wrong. I've tried switching my phone on and off

  • gordonsilvestro Gordon Silvestro (@gordonsilvestro) reported

    @O2 is there any information about the availability of 5g signal and when it will be available in my area, postcodes EH52 and EH54

  • asteelbath Alastair Steel (@asteelbath) reported

    @O2 I've spoken to 202 twice this month and they've given me all the usual guff. Apparently you are upgrading! Presumably degrading the service first so that the 'upgrade' seems better. If you can't keep the basic service working, tell people in advance.

  • DiWhite7 Di White (@DiWhite7) reported

    @O2 I’ve got a mobile wifi O2 pocket hotspot and haven’t used it for a couple of years. It’s now showing a red network indicator. Does this mean the payg sim will no longer work?

  • kyle_harring Kyle Harring (@kyle_harring) reported

    @O2 if an advisor puts you on hold for 10 mins for no reason, is it safe to assume they’re trying to get you to hang up?

  • LeightonTreagus Keyser Söze (@LeightonTreagus) reported

    Can you please, for the love of God, sort the mast problems out in BN14 0TR @O2. This is the fifth occasion of intermittent coverage in 12 months. Your engineers either have no idea what they're doing or your using a mast from the Mary Rose

  • Elmodfz Becky (@Elmodfz) reported

    @O2 It's still broken. I'm with tesco but I know they use your network. Plus my friend is on o2 and has the same problem but only in this area.

  • _therailway Joel Hardy (@_therailway) reported

    @O2 why is data signal in New Brighton so poor when it gets so busy! I should not have an issue with data

  • fuzzyslippers11 rebecca (@fuzzyslippers11) reported

    @O2 when you take out a contract phone how long before you can cancel the sim card and change network?
