That is terrible, honestly I'm sorry for what's happened to you. I've never had to deal with PayPal as a seller, of I have been lucky and got the payments and the shipping has been all right.
I can't even begin to imagine how much you have lost. I'm really sorry, honestly.
I'm going to use your case for my next post, also another one that is even more horrible. We have to raise awareness and try to change something as this can't go on.
Stay safe my friend!
