HDFC Bank — Gift card expired

Dear Team,
I would like to renew my gift card or please revert the money to the owner of the HDFC account.
I went to HDFC bank nearby, they were telling they cant do anything and money is gone.
There is no ethical for using money of a person if it is not used by the gifted person. If I didnt get the gifted money I request you to redeem the money back to the corresponding person. Or issue me a new HDFC gifted card.
Please do the needful.
The reason I didnt use the gifted card, is that I was in US and I recently came back and I happend to see this and I am unable to use this card.
Please help me.
