Glass flew off during very powerfull dry cycle

CAUTION REAR GLASS FLEW OFF DURING AIR DRY
FRONT LICENSE PLATE BADLY BENT ALMOST OFF
ANTENNA COVER FLEW OFF

I took my 1989 Aerostar van through the wash and at the air dry cycle
The air velocity is so strong that the rear glass of my van flew off.
I then also noticed that the license plate was severely bent and barely hanging by one screw, and also the cover that is clipped to the radio antenna base also was missing.

I filled a incident report at the office
The manager called me and informed me that they are not responsible
So I am on my own to repair their damage.

A 7.00 dollar car wash turned into a 150.00 bill using a used glass from the auto wreckers.

Also the van was still dirty after the wash.
