I recently rented a car with advantage and they kept my deposit. They upgraded my car without telling me and when i got the bill they deducted the upgrade. When i called the main office they said that since I had signed they would not give me my deposit back. It is a shame that for $200.00 this company would do something like this. I am going to file a complaint with the BBB and with the state attorneys office for unethical business transactions. Stay away from this place.
