Business ProfileforBridgeport Hobby Sports Cards

The purchases I made on June 29th were in the amounts of $555.96 and $463.35 and were for sports cards from the owner of the business (*********************) doing live ******** breaks. I paid for him to rip open and ship one hobby box of Panini *********** Cards and one hobby box of Panini Crown ********* Cards. He ripped them open and it turned out to be approximately $1,500-$2,000 worth of cards. He sent me a tracking number and I waited for the package to come. The package never made it to me. It returned to sender (he sent me a picture of the package with a fake looking sticker on it saying there was no contents in the package). I have tried to resolve it with him to issue me a refund due to him not protecting his sale and putting insurance on the package in case it didn't make it to me (which it didn't). The tracking number is **** **********************. I have done everything possible on my end to track the package, do a missing mail search, call the post office, etc with no results. The seller then accused me of receiving the package, ripping it open, taking the cards, and sending it back empty. He has not been professional about the situation and is trying to put all blame on myself and the post office so he doesn't have to resolve the issue. The only type of resolution he offered is to put me in future breaks or send me other cards...but why do that if you don't claim responsibility. I was clear I wanted a refund, not other cards/chances at cards.
