    Scam Warning - if you with O2 and you get a call from this number 0333 188 2196 just hang up, it’s a scam. They are trying to get you to give them a security code which O2 explicitly advise not to share with anyone including anyone from O2. #O2scam @O2

    @O2 It fixed itself yesterday morning. Not sure if it was an issue with the app & website or just a lot of user traffic. If it happens again ill take screenshots. Thanks

    @O2 The items in cart were all from the linked section. The problem wasn’t that it wasn’t taking the discount off, it just wouldn’t accept the code to apply to the cart. In red it said “Oops! The promo code you entered is invalid. Please check the code and try again.”

    Third working day unable to receive calls and text messages to my phone, 7 calls to customer services still not working. Not great for a freelance photographer @O2

  • JasmiineReign Jasmine (@JasmiineReign) reported

    @O2 i was advised to cancel my direct debit before my bill date and set it up a few days later - after a huge mistake (my bill had a £52 charge on it), I set it back up over the weekend and paid my bill - and now you’ve cut me off? Can you help?

  • LarderCotswold The Cotswold Larder (@LarderCotswold) reported

  • AnnaGordonPics Anna Gordon (@AnnaGordonPics) reported

    @O2 No just not working all the time. I need it for my business. It’s unacceptable. I will give it a few more hours then will cancel my contract and move to another network.
