Avis Rent A Car

I was told that we would only have to pay $ 240 for a 7 day rental with a 2010 Hyundai Elantra. The owner said he is giving us a good discount so of course we thought GREAT! After renting the car for a couple of days, I checked my bank account during our trip to DC, I was charge with $ 636! So my husband called to have them adjust the amount because it in INCORRECT. They said «ok» but when we returned the car, they slap us with a $ 450 dollar bill! This place is ridiculous! Now we have to go back & forth and show them our receipt just to get our money back. What a pain in the butt. Just because they have our credit card infos, they think they could charge us with anything! We was told to get a discount but yet, it was nothing but a scam. NEVER AGAIN!
