Alamo Car Rental Alamo Damage Recovery Alamo Damage Recovery charging me for fraudulant damage to my rental car Atlanta, Georgia

     I rented a 2009 Dodge Nitro from the Ft. Myers, Fl. airport for one day.  I did not opt for any additional insurance.  I looked over the vehicle before I rented it and proceeded to the gate that was attended by an Alamo employee.  I indicated to him that I noticed a small scratch on the bumper.  He said I was all set. I drove to Miami and turned in the rental car at the Miami International Airport.  During the checkout process I was informed that I had to turn this slip inside the office because of vehicle damage.  I informed the clerk inside that the damage was reported at the time of rental.  They said, "Okay sir, your all set, just sign here and you'll be on your way".  I recieved a letter indicating damage to the vehicle I should contact my insurance company.  I phoned them right away  (Alamo Damage Recovery) and was giving awful customer service they told me nothing regarding this "claim",  I was disconnected and I did not hear back for about 6 months.  I recently received a notice of Total amount due: $1030.20 for vehicle damage.  After reviewing their claim it looks like they replaced the rear bumper?  The scratch that I noticed was on the front bumper.  I phoned the damage recovery unit contact person (Carolyn) , she informed me my claim has already been turned over to collections.  Please be aware of this complete scam.  Is my credit now going to suffer?  I will not pay a dime on these fraudulant claim by Alamo.
