FED-EX ground and SMART POST..........It travels around the US with no place to go

I bought a 600.00 piece of audio to be shipped by Fed-Ex ground....Some how the seller decided to ship it Fed-EX Smart Post....Which is not "Smart".........The package leaves Alabama and travels for days and ends up in Troutsdale , Or which is a depot for Fed-Ex.......It lays in there for 4 days untel someone sends it over to USPS.....Now the tracking number doesn't work anymore so I don't know if it will ever show up...... I took the  tracking number to the post office and they can't track it ether.......Now you would say that the tracking number system is different, but this package has always had a USPS tracking number (22 digits) that you could only access through the Fed-Ex tracking system.......The people tell me when it is handed over to the Post office then I can access the tracking number through the USPS system......Do you think I'll ever get my package or my money or anything ?????   Beware "Smart" "Post".........POISON FOR SHIPPING
