Reliance Trends — Unused gift cards.marked as redeemed

Address:	Bahadurgarh
Website:	Reliance trends

There was a gift card of reliance trends purchased 4 months back and it says validity of 6 months .when i went to cash it in reliance offline store it says already redeemed..but i haven't used it and it is a very bad behaviour of reliance trends to say a non used gift card as already used
