Paypal has given me a lot of grief when it comes to bitcoin related sales. They made false claims about my account, held my funds for no valid reason, and when I submitted the documentation and waited (3 months later) still they apparently failed to review my documents.
I have evidence that Paypal has ignored my submissions.
After being on hold for about an hour and discussing the situation and trying to resolve the issue, they got upset and "bitchcoins" came up, I said "I'm sorry?" and then the guy goes off on another subject.
