Paypal has a time restriction on how long you can file a charge back. It was 30 days from what I recall. I ordered an item from EBay was shipped from China. It never arrived. By the time I went through the EBay channels it was past my Paypal window to get my money back. Scammers know how to work the system and will string you along better than a Nigerian businessman looking to cash a Cashiers check. For the fun I went down that road until I offered to bring the money to him in person. Seems like I had business in Nigeria collecting for a partial refund of slave my great, great, great, great grandfather bought. I had the receipt or so I claimed. Truth the ancestor in question was a officer in the Union army but no need to go into too much detail. Once I offered to come in person, the scammer lost my email information and went away. It was fun while I strung him along.
