Dollar Rent A Car Review

Dollar Rent A Car: This is the second time I've had a problem with Dollar only to get offered vouchers. This time, I went to pick-up my car and they only had the PT Cruiser available in the class I reserved (which I hate), nothing in level higher, only full size (2 levels higher). He told me it was $11.99/day more, I said "no thanks" and I'd go to another rental agency. He said "wait, wait, since nothing available one level up, I'll give you the full size for $5.99 which is the one level up price". I said ok and rented. Later I noticed he charged me the full amount of $11.99. I brought car back (with 42,000 miles on it) and told them that the car shook pretty violently when breaks applied and they replied "well, we have to keep them longer now" and didn't even record the comment about the breaks and told me that I had to call the national customer service about the overcharge. When I did, they were only willing to give me $20 of vouchers though I'd rather never rent from them again. Dollar sucks as bad as a PT Cruiser.
