I rented a car for 12 days. It was not damage and when I returned it I was given my receipt. No damage to the car was mention by the two agents for Alamo. I rec'd three weeks after a letter from Alamo Damage recovery Unit which stated my car was damaged. In the letter it does not state what the damage is or any information. It more like a form letter with my name and a claims number. It is telling me to contact my credit card company since I refused the CDW for payment. The letter has a threatening tone to it.
