    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @o2 can’t you tell me why your customer service is so appalling called twice after I was given this number 034480490202 answer the questions and then Bye thanks for calling

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

Latest outage, problems and issue reports in social media:

  • ArmyxAimee Aimee 🤍 (@ArmyxAimee) reported

    @O2 the launch of the s22 ultra has been a failure. Customer services have no idea when the launch is/was. Telling me that it could take a further 4 weeks for my order. If I order for preorder I should expect my order by today or a notification regarding my order and my free gift

  • Teeq8 Teeq (@Teeq8) reported

    @SamsungUK Pre ordered weeks ago @O2 absolute joke of a company telling me I have to now wait 4 weeks.... literally PRE ORDER so you know exactly how much is needed before the release date and you coudlnt fulfill it!?!?! Sack your head of logistic, operations and fulfillment, awful.

  • AngharadJ5 Angharad (@AngharadJ5) reported

  • VMO2News Virgin Media O2 News (@VMO2News) reported

    Our thoughts are with those affected by the awful events taking place in #Ukraine. To support our customers on @O2 and @virginmedia, we've removed charges for data use in Ukraine and will credit charges for calls & texts to & from Ukraine and the UK.
