H & M Voucher

<p>I received a R200 for H&M Store from a friend and I lost the card but I still have the receipt which clearly states the funds in the voucher & the voucher number. I approached H&M for assistance and I was told that the card still has the credit, and that whenever I had time I should come to their Sandton Store and they will give a new voucher. A few minutes later, I received a call back that I need to give the card number I used to buy the voucher and then I repeated to them that it was a gift so I can't give them a card number. The consultant asked me to write an email to that effect, thereafter there was no response for a day. The second day I enquirer why is the silence....nothing...the third day....I asked again and I was told that there's nothing they can do for me, as vouchers are treated as cash. My question is why did they agree to help and the retract?</p>
