I avoid UPS at all costs. The last piece of gear I bought was shipped via UPS (I forgot to specify against UPS). It was double-boxed by the seller yet arrived damage anyway. From what I can imagine based on the damages, I estimate the box was dropped from at least waist-high onto a concrete surface. Fortunately the amp was repairable and the seller even had replacement parts (surprisingly). I didn't even bother with the claim expecting a similar situation as yours. I made the repairs myself with the parts sent to me by the seller.
I much prefer FedEx Ground or USPS. With USPS, filing a claim is so much easier than anywhere else.
