    @O2 How did this shit happen

  • sjetaylor Sarah Taylor (@sjetaylor) reported from Loughton, England

    @Johnny_Slack I’ve been with @O2 for 20+ years but once contract expires in August will be moving suppliers as they don’t look after their customers - no loyalty perks nothing - poor coverage where I live and work so it’s bye bye

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

    @westspice @O2 Awful service for me today!

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • m0rven morven (@m0rven) reported

    @O2 - I need to reactivate my dad’s PAYG sim, can you help with that? (He doesn’t do technology, the sim used to be mine!)

  • v93704347 v (@v93704347) reported

    @O2 my monthly contract recently ended so I asked to switch to pay as I wanted to keep my current number You guys sent me a new sim with a new number I rang up to swap numbers and they told me it’s done but It isn’t as I cannot receive calls or text on my old sim no more help!

  • r_thurston Rupert Thurston (@r_thurston) reported

    @O2 thoroughly unimpressed with your o2 recycle service and now understand why you keep it at arms length. Had sent off my old handset. Now just noticed money taken back off my bill without communication or return of handset!

  • YuriBoy70984836 Yuri_Boyka (@YuriBoy70984836) reported

    @O2 I've recently joined o2 from three network taken out a 36 month contract Samsung note 20 ultra at around 61 a month no 5g in my area called up to be offered a measly£3 discount a month wish I went with sky or ee better perks better coverage cheaper.

  • Robot_Logic Robot Logic (@Robot_Logic) reported

    @O2 Basically you're banking on people getting the 'free' Disney + and then forgetting to cancel subscription. And you're just misleading people, when the last thing they need if choosing some 12-24 month contract, is the confusing mess you've deliberately engineered.

  • josieshmelon Josie (@josieshmelon) reported

    @O2 tried to add an Apple Watch to my contract and it gets to the review and then when I press submit says there’s an error and to call 202 but they can’t do anything? Is the website down?

  • deanprobert89 Dean Probert (@deanprobert89) reported

    @rhianlinecar @johnthejack @O2 That’s o2s biggest problem. Any town or city centre the signal is terrible not the south coast. Need more investment on their network. 4G is abysmal. As soon as my contract is up I’ll be jumping to Vodafone or EE.

  • Daggy332 Daggy33 (@Daggy332) reported

    @O2 I'm thinking of joing your network with one of your SIM only deals. But will it support esim. I have galaxy watch and its important this is supported with my phone

  • KellymarieSelb1 Kelly-marie Selby (@KellymarieSelb1) reported

  • ChezPoule Deb (@ChezPoule) reported

    @O2 Trying to pay off my device and buy a new phone. Spent all day waiting for a call but nothing. Can't pay off online and the App never works on my device. Want to speak to a real person. Frustrated
