Having a problem after shipping a part

I like inkjunkies idea except for the check thing!!! I got another idea, how about telling him you resent the part to the same incorrect address and tell him to go pick it up there. Or tell him you never got it back and don't know where it is. Tell him to check the incorrect address to see if it's there. Then just sell the part and recoup your aggravation by helping someone who really needs the part and is grateful for your time and effort!!! Deal done... "I don't know where your part is, I sent it to the address given"!! You don't need this aggravation, you're one of our best and we're on your side!!! Turn him over to us and we'll find the right solution!!! Geof
