I've filed 2 claims...they're not too bad...just not very fast.
The sender will have to fill out paperwork and a UPS rep will come out and inspect the damage. They will issue a check to cover the damage to the sender and you'll have to collect the refund or get a replacement from the sender. :comando:
If you bought them from a vender, email them pix, maybe they'll be good enough to send replacements in them meantime.
