Call FedEx during business hours and explain the situation. Ask them to have the driver's supervisor call you. If the shipper label was printed out using their on-line system, they will be able to see exactly what address was on there and they'll probably reprimand the driver for failing to deliver those packages if all those addresses were in fact correct. Also as a corporation, they won't tolerate racist comments by their drivers. Tell them what the driver said and insist it was racially motivated. Sounds like you have nothing to lose. They'll probably assign a new driver to your route if that driver has had other complaints.
