The receipts are phony, no doubt about it. He must have used our names as reference to something entirely different, which was actually sent to other countries, but it sure wasn't the non-existing ppc cards.
Example:
He goes to postal office and sends a package to Sweden for let's say some music CDs, and in the comments/reference section he puts "Jose - PPC" and then sends THAT receipt to you when you complain about not receiving anything. He makes himself look like he actually sent the package to you, but it's all a reference section trick.
I can only hope that Police could do something about this.
