I now have £20 worth of loyalty vouchers which I cannot use as the checkout tells me my card is invalid! Even though the vouchers and card number appear at the checkout and clearly are valid! Customer service are useless. At first I was led to believe that mine was a problem specific to me, but my last message from customer service seems to indicate that this is an ongoing problem. I note that other people leaving reviews have had the same problem. Then today I actually received a flyer from Monsoon promoting their loyalty scheme! I really am beginning to wonder if this loyalty scheme is actually real or just a scam to get people to spend more. I suspect my vouchers will have expired by the time they fix their system, if indeed it is ever fixed!
