    @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.

  • 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

  • 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.

  • meribelman Peter Williams (@meribelman) reported from Penarth, Wales

    @virginmedia I would happily self serve online, via a browser or app, as you incessantly encourage me to do, but when the page says “oops something went wrong, we’re unable to change your package online”, its very frustrating. @O2 will help you soon!

  • JdBowns91 Jade Bowns (@JdBowns91) reported from Barry, Wales

    @O2 on the website it says to contact your customer services to change my name and other issues I want to discuss yet the only way I can get through to someone is to say I’ve had fraud occur! All I want to do is speak to someone why is it so hard. Chat is also unavailable

  • 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.

  • CatTPeters Cat Peters (@CatTPeters) reported from Penarth, Wales

    @O2 come on please! I’ve now spoken to 3 people and now been out on hold for almost an hour. Unbelievable customer service. I literally just need the PAC code.

  • CatTPeters Cat Peters (@CatTPeters) reported from Penarth, Wales

    @O2 I’ve just tried again, it’s not working. Please can someone send it to me please. For a simple procedure it has become be my stressful, and nobody seems to want to help!

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

  • 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.

  • vodkadebs Debbie Katy Seymour (@vodkadebs) reported

    @O2 have been trying to claim on my insurance for a week now, most O2web chat advisors are great however the one I have just had contact with… not so nice! Have been told claim team will be in touch, nope. Try calling direct and get passed around with no help!

  • sunflowerninja Nina Russell (@sunflowerninja) reported

    Has anyone ever won @O2 Priority app competition? I swear I’ve entered every single comp I’d like to win since I’ve been on the network (over 10 years) and never won a thing! Am I missing a trick?!

  • andrew_saval Andrew Ferguson (@andrew_saval) reported

    @JackEd84283152 @Techusiast Still no sign. I’ve no idea why @O2 are so slow

  • Bethmccabe6 Beth McCabe (@Bethmccabe6) reported

    @O2 please can you get in touch. I've had no signal now for 8 days. Your website is now saying you don't know what it will be fixed. I am only able to use my phone when connected to WiFi

  • BruceOnlyBruce Bruce (the legend) ✨ (@BruceOnlyBruce) reported

    My favourite thing about being an @O2 customer is when your device contract runs out and they sell your data to loads of dodgy companies, so you get unwanted calls for weeks. (My actual favourite bit is when you’re finally free and can choose a different network.)
