Firestone Complete Auto Care

I came in for an my scheduled oil change. I get a call that there's problems with my tires, which is not the reason I am at firestone. 1.5 hours later I ask what is taking so long, apparently the lift that my car is on is broken. I have waited 3 hours here so far and my car is still on the lift. This is unacceptable and all I have been compensated is that my oil change is for no charge and a free oil change in the future. But I guarantee I will not be back to get my oil changed here. This is unacceptable.
