any lawyers in this forum care to give an advice?

Delivery company drivers share a kinship with bank tellers......they both develop an indifference to the valuables they handle on a daily basis. Of course, I'm not suggesting that bank tellers are careless with money, just that the money becomes only another thing that has to be dealt with. So it's not surprising to me that delivery drivers seem to be ambivalent about whether the item gets damaged or not. If an item is properly packed, only the most Neanderthal treatment will cause damage to it.

I just packed up and shipped a 12" sunfire sub. those subs are notoriously difficult to ship, and have arrive, undamaged.

I had to custom make the packaging, over time, as I thought about how to go about it.

When I was done, I had a 55lb box that could be stood on, on any side, and more.. and even bounced down a set of stairs. Which is how an item should be packed, if one is going to try and ship it via UPS or FED-EX or USPS.

moto_man is correct in that you need to go after everyone. During the time I worked in insurance, all claims made by condominium owners for things that went wrong on a major scale sued everyone involved with the construction, no matter how small the job was. 

It was like a wake up call that the owners weren't messing around and forced all parties to get together in a timely fashion, eliminate those who couldn't have been involved, and bring it to an end in a timely manner.

Once they have to respond in court, they start to behave.

All the best,
