I was unable to spend my GIFT vouchers at the checkout. I sent several emails and no one gave me a helpful answer. I tried to escalate the issue but they do not have phone number. I now have £150 of gift vouchers that I can't spend how I want.
You're not allowed to use 2 vouchers at the checkout and then if you have a discount code money comes off your voucher... - is this legal?
No help - do not buy gift vouchers or go somewhere else.
