Buyer claims to go on vacation a lot. I shipped 2 huge boxes of books weighing 70lbs each, I gave free shipping. Buyer never claimed boxes and they were returned to post office and return shipping cost was needed to claim packages as they were shipped media mail and not covered to return for free. I could not afford to ship these back nor claim them from the post office. I told him it was his responsibility being he waited over 3 months to tell me he never got them. 6 months later he contacts me threatening me to refund him for the books I stole or he was doing a credit card charge back. Thank God I did my home work and he waited too long to screw me. The post office seized the books and in the end his scam only cost him money!
