Purchased Website on ebay

[joelous]

I won a auction on ebay and it included 13 websites and 300 hosting customers, the 13 websites were delivered instantly but the auction stated that the seller had 90 days to delivery the 300 customers, it has been 90 days and the seller stated that the 300 customers were lost during the transaction I paid $870 for the auction is there any way to get my funds back it has been 90 days so paypal will not help and can the seller be charged in a criminal court for fraud or deception, the seller delivered the websites but no customers??
