Complaint Review: ABC GIFT CARDS

I sold this company a 50.00 gift card to Microsoft on July 22nd, I filled the paper work out and securely mailed the card that day, It is now the 30th and they state they have not received it as of yet. I also was curious as to whether they had any for sale on their website to see how much they were going to sell it for after their offer to me. Well, on the 22nd they did not have any available.....

But, on the 30th they all of a sudden have a 50.00 Microsoft gift card available for sale  for 44.00 ... Could this be the gift card i sent them?? It seems very suspect that they all of a sudden have a 50.00 gift card for sale on their site and they claim they never received mine. I am filing reports with everyone i know as i am NOT taking a loss on this transaction. This company is the worst ever to deal with.
