Some months back I received

Question

some months back I received 2 TV Convertor Box tickets.I put them aside to wait for the U.S. government to send me the $600.00 check I had applied for. By the time the check arrived,the tickets had expired and now that I have the money to buy the convertor boxes,the tickets (value $40.00) have expired and no one dealer will accept them. They are still here still packaged as received and except for the expiration factor of no value. Can you get these replaced with useable tickets??
