I would just create a thread saying DONT DEAL WITH THIS GUY. I am sure that it will remain. But then it goes back to checking Reefer Ratings. If someone just appears on the site and starts buying up stuff, maybe people should be careful.
Also cash would be better for the most part, but that is hard sometimes!
Unfortunately you learned the hard way. I would call the bank that you have your PayPal account linked with. And tell them that you want to block PayPal that you are in a dispute with them. See if the bank can help.
I am just trying to figure a way. Paypal has to be able to do something since the sale was soooo long ago.
