My son and his wife bought a Smartbox voucher for our Christmas present for looking after their children. Just tried to book the event and the voucher comes up as invalid. Called Buyagift and they said they need evidence of purchase to activate and asked that my son or his wife to call them. I explained we don't have the receipt as it was a present and my son may not as it would have been purchased 4 months ago. My family is now searching for the receipt. Looks like a scam to me, how do these people get away with it!! Do not buy anything from them it won't work!!
