I get where you are coming from, it is a frustrating situation. The first payment absolutely should have been refunded. He had to for seller protection from PayPal. That was your fault. So you shouldn’t have started arguing with him for your mistake... honestly, there was nothing he could’ve done about the funds held up by PayPal and you were wasting your time arguing with him about it. Seems like if you would have accepted the funds being held up because of your mistake, you would have a knife on the way to you. I went through some customer service/management training for my job. They teach you to listen, in this case, read, and wait a couple of seconds (3) to take in what you have heard from the customer/person you are dealing with. If you read half of a response and are already forming your response, you don’t take the time to comprehend the information being presented to you. I would have had to of read the messages you wrote to have any insight into if I would have kept the deal going depending on what you did or did not say to the seller. What I will say is, reading some of your messages here, while understandably you are upset, made my head hurt a bit.
