    Hi @O2 as you’re aware I’ve been on no service now for over 3 weeks, any updates yet or? Or do I just continue to pay £60 a month for a phone I can’t use unless I leave my house ?? If someone with a brain cell can get in contact that would be fab 👍🏻

  • 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 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.

  • 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.

    @Angel_McLachlan @GavNewlandsSNP @O2 Unfortunately didn’t work for us. Reset both the ee and o2 phone and nothing which is a shame because o2 don’t believe there to be any known issues 😫

  • seantrent Sean Trent (@seantrent) reported

    @O2 I've been trying for 3 days now to give you my Vodafone PAC code to port my number on to my new O2 sim. I've been hung up on once, and twice told that you have system problems & to call back the next day. How long will your systems be down for??

  • SpankyWhizzbang SpankyWhizzbang (@SpankyWhizzbang) reported

    @O2 11.7% air time increase!?!? Tone deaf - some folk could really use some support right now as things are getting hard enough without blatant profiteering - you could have absorbed some of this. You've lost a loyal customer of 15 years when my contract ends #o2priceincrease

  • Cami_85s Cami (@Cami_85s) reported

    @O2 @asif_choudhury O2 you are so slow to responding DM's that I might get an answer when the next Christmas comes. It has been 3 days and we are at the stage where you confirming my home address. Basically you ask me 1 question, I reply and then wait at least 5 hours to get another question...😒
