USPS has........

I used to live on 2 acres on a major intersection west of Greeley, Colorado.I had a street address but due to Highway widening my driveway got moved from the street side to the Avenue side of the property.USPS and UPS had no problem figuring it out.However FEDEX for the life of me couldn't. Even though my mailbox had the address in 5 inch letters anything from FEDEX would get "Bad Addressed". It's not who the service is but who they hire to provide that service.
