Scanman if the engine you bought is bad and they refuse to help you out then contact your credit card company and try to dispute it
I did this the other week with a scam purchase I made on Pay Pal payment and they my credit card company
did agree with me and reimbursed my funds that Pay Pal would do nothing about..
So Pay Pal is doing nothing about scam asshole that is on their site stealing money ..
I had taken pictures of the whole conversation and sent it from Facebook messenger...
Our country and how sad it has become...
