  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia I feel for you, if @O2 and @virginmedia do merge, I'm leaving at the earliest opportunity. @virginmedia leave me a little cold and with no confidence as a customer.

  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia @O2 Good luck to you and don't take any sh*t, you should be fully compensated for the absolute inconvenience. We had a little problem with our provider and they where excellent, understood the issue and before we asked they compensated us.

  • AdamLee2011 Adam Lee (@AdamLee2011) reported from Newport, Wales

    @O2 Already with o2 for my mobile and they are brilliant. This was for MiFi, someone recommended three but the signal is terrible. Waste of money.

  • Hayeley Hayley (@Hayeley) reported from Cwmbran Central, Wales

    @O2 is there an option to setup a direct debit without making a phone call? It used to be set up but for some reason didn't change when I used the Switch service to move banks and I'm fed up of being told I'm behind on a payment. Can I do it via the app? Thanks

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

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

  • 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?

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

    @O2 guys is there a backlog in complaints? I responded to a complaint on the 06/10/20 no reply, 20/11/20 no reply. I’ve now sent a further email today and I’ve no faith in it being responded to. Original complaint was 04/09/20.

  • 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.

  • Garethbird85 gareth bird (@Garethbird85) reported from Newport, Wales

    @O2 can someone from customer service contact me please

  • BCFCOLIVERDOG Oliver City Dog (@BCFCOLIVERDOG) reported from Cardiff, Wales

  • 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.

  • war_knockknock Ryan Warnock (@war_knockknock) reported

    @O2 8 days of financial threats and having my service cut off despite having paid my bill for 10+ years - any chance of a reply yet 🫠?

  • Superlism MC (@Superlism) reported

    @O2 hey, I seem to be an expert at finding where your network is terrible. How is it in central Maidenhead with 2 bars of 4G my download speed is 1mbps. Fancy putting a bit of work into your coverage?

  • adyefc Adrian Wright (@adyefc) reported

    @O2 Are you for real? There have been issues with the network in Preston for months!! It’s a disgrace, but as we are in the ‘north’ you lot won’t do anything about it

  • howard_shinn Howard Shinn (@howard_shinn) reported

    @O2 @Ruthedwardsmp2 what are the government planning to do about this ever continuing problem, time and time again real fans are unable to get tickets, whilst other organisations seem to get tickets which they sell at inflated prices.

  • sazmeister88 Sarah 🚩💚🤍❤️ #WearAMaskYouStupidBastards (@sazmeister88) reported

    mad because both @virginmedia and @O2 insist that MK has full coverage with no issues yet central milton keynes is the only spot in Europe i can't get signal, it's been an issue every day i've been here for nearly six months, clearly there is an issue with the 4G coverage here

  • Sam_Halfpenny Sam Halfpenny (@Sam_Halfpenny) reported

    @EE your customer service is just as bad if not worse than @O2 I changed 7 days ago from O2 to EE and I now have two numbers, and two phones. I give up trying to get through to your tech department, it’s a joke.

  • RicMG99 Richard Greenwood 🔶 (@RicMG99) reported

    @sazmeister88 @virginmedia @O2 There is a problem in CMK, but I'm not sure if it is lack of signal or lack of bandwidth for everyone trying to use it. My phone regularly says it has G3 or G4 there, but then refuses to send/receive data. The signal exists but is useless for any practical purposes.

  • MattBroughton13 Matt_Broughton (@MattBroughton13) reported

    @O2 @MBBarlow Hi. Could you do the same for me? Having Sim trouble while overseas

  • nd_wells Neil Wells (@nd_wells) reported

    I had an O2 online agent ask for my answer to the security question. I said what’s the question, but he wouldn’t tell me the question because I hadn’t got through security. He’s kinda left me feeling that I am actually the idiot here, but more because I am still with @O2.

  • AbbyVictoria15 Abby (@AbbyVictoria15) reported

    @O2 As expected, it wasnt anything to do with any of that. O2 had disconnected my sim!! 35 mins on call to a premium number (thanks for having to pay crazy money to speak to o2, my actual service provider) and you finally reconnected me.
