  • 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.

    @jennifer268716 @O2 Amazing how the sales customer service guys can do callbacks, but when you need to resolve an issue with a manager it takes them days to ring you back! Currently on day 5….once they have your money comes to mind…..
