When working with Harbor on this kinda sh!t, make sure you have EVERYTHING is writing. Some years ago, I had a large order coming from them and they messed it up so bad, it couldn't be fixed. They tried to blame me, even though I had everything in writing. They wanted me to pay partially or just accept it and they'd discount me on my next order. I hadda get the entire order from another source and luckily the other vendor came through. Harbor still wanted me to pay for certain things, cause they said they made it for us, but couldn't help that we couldn't use it. I told them, the next time they call..... to call me at this number and I gave them my attorney's number. They never called, but I got statements for almost 2 years for that. I was just lucky, my customer was understanding and waited and the other vendor came through quickly. I still hadda discount to my customer for the delay, but we were all happy in the end. Hence, another reason for putting enough markup on things.
