I got bought vouchers for my birthday at my request and unfortunately two of them (for £40) don't work on the ASOS site as there is an error at their end. I've notified them 3 weeks ago, the first CS rep never even bothered getting back to me and all I'm getting told now is that they can't tell me WHEN they will be fixed just sit tight and wait to hear from them. I think this is outrageous they can't take peoples money and not honor the vouchers because of a system error their end ! BEWARE.
