I traded in my Honda Pilot, loan # XXXX, on XXXX/XXXX/15. The dealership who purchased the vehicle from me sent a check to Wells Fargo Dealer Services on XXXX/XXXX/15. Wells Fargo Dealer Services does not acknowledge receipt of this payment and refuses to research the payment without the certified mail receipt number. I have offered to send them a copy of the payment invoice, but they refuse to investigate.
