NUCAR rental cars are disappointing

I recently attempted to rent a car from your company on line and in the process off finishing the rental your system froze up and by the time I was able to complete the rental an hour later the price had went up *.** aday . I called to see if they could help me correct this and was treated very rudely and the call dropped and it was over * hrs until I got a text back saying she couldn't help upon picking up the car the windows were filthy I had to get glass cleaner and clean them I pointed out to the agents there was no spare tire in the car it had been removed they just blew me off I didn't feel safe going even to hoover dam with this car. I have rented from your company at least * yrs now but after this I doubt we will make it **Robert burky****-***-*****res * **********nu

I want a refund for the difference in what I was quoted and what I was charged

called and was cut off and never called back
