rental car

On 9-19-2008 i flew to Houston and rent a car from AVIS. First they gave me a Honda Accord with a dead battery, then they gave me a Chevrolet Impala with two front tires that are worn to the bone, and i did not see it. The car vibrated uncomfortably above 60 mph and i was so scared because the two front tires can blow anytime. I was so mad at myself because i did not check the tires and i was also mad at AVIS and wonder why they dare to give customer that kind of car with two worn-out front tires(two rear tires are good), why their stupid mechanic put two bad tires in the front? they do not care about customer safety?..so be carefull folks.
