After informing him I don’t send internationally, a year later he provided an Utah shipping address and I sold him seeds confirmed delivered by USPS. He opened a case for refund with PayPal saying he hasn't received them and that, I didn’t reply to a message(s) that he never sent to me. After PayPal ultimately ruled in my favor, he posted it was mistake and message me the same as he posted below on 7-8.
The only other post transaction PM was recently received about the second part my seed package that his friend spilt up arrived. Nevertheless, we still have a misunderstanding as he believes I was guaranteeing said seeds reach New Zealand, rather than Utah where I contracted to send them.
