My friend's incident occurred with UPS, not FedEx. Also, it turns out that they were sticking to their guns not to pay, even though a forklift had been run clear through the box. The reason he finally collected was not that the item was damaged. He had the guy who bought ship it back, and it got lost in the return trip. So, he got paid not because of their negligence in destroying the amp, but because of their negligence in losing it.
Amazing.
Do you ever wonder how these people with this "insurance adjuster" mentality live with themselves after finding every imaginable way of wriggling out of their responsibilities?
