A hold on the card means it has probably already been used. It is reasonable for the issuing organization to ask for a receipt to verify you are the one who bought the card. The hard part is the personal information. Do you give them the info of the person who bought it or yours? If the person who bought the card used it, then your personal information isn't a match and they'll decline to give you - the person who looks like you don't really own the card - the money. If you provide your personal information to a group that isn't really the help desk, your identity could be stolen, too.
