CardCash Sold me 2 gift cards that had zero balance after 60 days....I'm out $400. Brick New Jersey

I purchased two gift cards from CardCash (one from Chico's for $300, and the other from Panera Bread for $100). When I tried to use them two months later, there was a zero balance on both of them. I contacted CardCash on three different occasions. They told me that they tried to contact the persons who sold them the cards, but were unable to reach either party. CardCash says they have a policy that they can only gaurantee the cards for 45 days from the date of purchase.

They made no effort to reimburse or compensate me. All they did was keep repeating their 45 day gaurantee policy.
