Sorry to hear about your trouble.

I own & operate a electric motor business & have trouble with
UPS shipping new motors, at least 75% of the time they are
smashed or bent up.
Now if they deliver a new motor to me I make the driver stay
till I open & make sure everything is OK.
For the last year & a half I try to have things shipped by
FedEx, I have had no trouble with them.

When I ordered my 9000 PRO the first 2 came in smashed
the 3rd one ended up in the state of Washington. & I live in MN.
So I told my dealer to have the next one sent by FedEx &
that one made the trip in perfect condition.
So I am NO fan of UPS.

If you had the extra Insurance I would think you would have
a good chance of getting paid.
Keep after them.
Wishing you the best of luck
Denny
