During the past year, I have had several FedEx orders, both Express & Ground Service, delayed due to "can not locate recipient".
This seems to be a catch all phrase for FedEx when, for whatever reason, an order has gone astray, has been lost, or when there is simply not enough cargo to warrant a delivery, to a certain area, until additional items can be added on board the delivery vehicle.
I have been advising all shippers, that I do business with, "Not Ship to Me using FedEx" and I likewise, NEVER use FedEX for my own deliveries.
I have found their service is highly over-rated.
