When I order my bracket, I put the wrong mailing address. So the post office returned it to Fast Boat Parts. Armen the rep. For Fast Boat Parts, Immediately returned my call & has been doing a great job of watching for the returned bracket, keeping me informed of the status. The first bracket was delivered quickly & Armen has been very nice & thoughtful in assisting me with getting another bracket mailed to my correct address.
