I arrived at Charlotte and I presented a valid coupon for a free upgrade , The lady first tells they can not give out any upgrades because all the cars are taken, Then She tells me if I would like an upgrade I would have to pay more, So I told her that she just said all the cars were taken. Basically I was lied to and she just didn't want to give the upgrade. After I went to get my car it was supposed to be a compact car but it was an economy car and was super tiny like a fiat 500 size. I was very unhappy and regret doing business with them. and the car ran terrible, I should of paid more and went somewhere else.
