[PLEASE READ] Dirty Disputes

Recently I've dealt over $1,000 in virtual merchandise and to my surprise I wake up to a couple disputes due to "Unauthorized Payment" for over $700+ lossed. I have their confirmed address, if I send them a box with something random in it and provide online tracking information will I win? Or should I just simply call PayPal and tell them to check the IP's.

I really need to get this money back, thanks in advance.
