Valet damage to rental car

Ok so this is a new thing for me. I valet parked my rental car today at the Double Tree in Downtown Atlanta. A couple of hours later I called down for the car and when we came down they were just pulling it around the corner and when I looked down I noticed "sideswipe" or curb damage on the lower bumper. I contacted the manager and filled out and incident report and was told the insurance company would get back to me. As far as the damaged to the car I took the damage waiver on the car (I am required to.)

Can anyone offer any input on what's next, or if this has happened to you what was your experience.

Thanks all!
