I don't think I have any recourse at all. My husband's car blew up and he's been using mine. I thought I could get away with throwing some stamps on an envelope and leaving it in my mailbox was a great way for me to be able to get the thing in the mail, because I don't have my car to be able to go anywhere, I'm stuck here. He's leaving at 6 AM before the post office opens and coming home several hours after they close. I wasn't about to buy an Uber ride to the post office. No tracking for first class stamps. Hosed.Did you involve customer support? There are seller protections last I knew.
