Just To Add: If its a O2 voucher they can be a pain to work straight away, they need several attempts in most cases (it may say voucher invalid) but it’s not invalid as it’s just a glitch/problem in the giffgaff system or sometimes it says invalid but its already been added, please do check your balance and payment history
Check your payment history:
