I submitted payment to lightinthebox.com for a set of cell phones. I payed through paypal. The company contacted me and wanted copies of my credit card (which I did not use) as well as copies of ID (such as drivers license, passport, etc.)
I felt very uncomfortable with this and contacted paypal. They said they Do not provide merchants with customer information, and any attempt for a company to get personal information from a client who payed with paypal - is most likely a fraudulent company!
I requested my order be canceled, which took them a couple days to realize. I finally had to file a paypal dispute in order for them to cancel my order. Since then they have sent 2 emails requesting that I cancel my paypal dispute against their company, and that i should "trust them." Their letter also stated that it could take up to 45 days for my refund to be given back to me!
