I ran a side business selling collectible card games for twelve years, answering emails and filling orders 6-7 days a week. On rare occasion I would make a mistake and send the wrong edition of a card or forget to mail one of the ordered cards. When the seller would contact me I would fix the error and apologize for the inconvenience, sometimes offering a discount on a future purchase. We’re all human and make mistakes, but I never ignored emails. The seller Brt probably did receive the sellers complaint email but forgot to follow up. The best way for the seller to respond to the PayPal claim would have been to apologize for the mistake, that the missing items were going out in the mail tomorrow, and here is the tracking number. Clearly the seller over reacted by banning the buyer from doing business with him again for his mistake.

All of that said, the buyer Justpin was unhappy with the seller with three of his previous purchases so he should not have been placing a fourth order with the seller.
