Express Rent A Car

I have rented here before with no problem. The cars are raggedy and could be a little better. They pretty much rent to anyone. However I rented a car one day and decided to keep it the whole week. I called to let them know i’ll be keeping the car and asked the procedure for returning cars after hours. She told me no problem just park it in the back and leave the keys as they have spares. I confirmed I wouldn’t be charged extra for leaving it after hours. She said no. Friday comes I return the car after hours. I call sat morning to make sure they have the car and the keys. The girl in the front states yes however you have a balance of 66 $. I was confused the charge is 25 a day why do I owe 66 $. She stated because I didn’t return the car Friday before they left I was charged for all of Saturday. That is ridiculous when I didn’t have the car Saturday and when I asked prior to keeping the car why wasn’t I told this. Especially after I asked. She seem to have an attitude because I kept questioning where this amount came from. After going back and fourth I decided we weren’t going to get anywhere. I told her I won’t be paying it or renting from them again and disconnected the call. Never again will I rent from here.
