  • 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.

    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 👍🏻

  • chrisquinny01 Chris Quinn (@chrisquinny01) reported

    What started as really bad customer service from @o2 one hour ago has turned into good service from the 3rd and 4th person I’ve spoke too, Aaron and Tomass (Sorry if spelt incorrectly) were very helpful and the situation is out of the hands and they were apologetic

  • Happyengland79 Shana Hendry (@Happyengland79) reported

    @O2 Not helpful in the slightest. How about u maintain the masts so we don't have to be without data, that we pay for! No compensation for lack of service despite taking 20mins to load a page if I'm lucky. O2 is messing with my work & that's unacceptable!

  • sarahtweets sarahtweets (@sarahtweets) reported

    @O2 what is going on with signal in YO7 lately, over a week of intermittent signal. barely 3G sometimes can hardly do anything! so glad i upped my data last month 🙄🙄

  • SchecTom ✊🏻✊🏿Tom✊🏿✊🏻 (@SchecTom) reported

    @O2 how do I get in touch with your customer services? Massive complaint to make! Whoever I got on the phone earlier in the payment management team was the helpful person I've ever spoken to in my life.

  • dantheman19970 dan (@dantheman19970) reported

    @VodafoneUK disgrace of a company paying for a device that doesn't work properly I'm not sending it off for repair and going without a phone shame on you I'm moving all of my lines to @O2 a lot better then @VodafoneUK

  • kirstyboo79 kirstyboo (@kirstyboo79) reported

    @O2 The bundle was for @HuaweiMobileUK wireless charger, wireless earpods, and wireless car charger. I don't particularly care about the car charger but I specifically bought the phone and stayed with @O2 for this bundle. Waiting months until it's too late to return/cancel isn't ok.

  • SchecTom ✊🏻✊🏿Tom✊🏿✊🏻 (@SchecTom) reported

    @o2 I would like an email for your customer services team. Massive complaint to make. Whoever I got on the phone on your payment management team earlier was the least helpful person I've ever spoken to in my life.

  • BertyBoyCAFC Paul Reynolds (@BertyBoyCAFC) reported from Gravesend, England

    @O2 hi my phone been saying no service all day. Was told was nationwide issue but I seem to be only person with this at moment any ideas

  • LadyDarkKnight Amy ✨ (@LadyDarkKnight) reported

    @O2 I’m not looking to chase and I’m sorry but I really want to get this issue fixed ASAP it’s causing me to get close to tears of frustration. Please respond to my DM.

  • lesliealee Leslie Lee (@lesliealee) reported

    @O2 Seems there was a minor outage of some kind last night. It seemed to resolve itself later on around 10PM. Thanks for the response
