Blue Zebra Shop Never received my item and they stopped respoonding to my emails New York, New York

I ordered a discount through lifebooker and it took me to this shop. After paying for the item, i waited two weeks, checking my account with them. It said "order processing". So, i emailed them and told them to ship my item already, and they said that it was delivered and gave me a tracking number. I called the usps and they said it was delivered as well. But i never received anything. After almost a month i emailed them again and they didnt respond. I paid for an item that i never got to use and even though it's not such a large sum for me, it is still something i need to resolve.
