Rented a car from Dec 20 to Dec 22 but couldn't return it until Dec 23. When I came to return it on 23rd the location was closed and they didn't have after-hours drop box. I had to leave town and was in a rush. I ended up leaving vehicle in their parking lot and hid the key in an electrical outlet behind their building. I then called them and left message on their voice mail saying I'm returning the car and explaining where the key was. Next day nobody called so I assumed they processed it and everything was OK. January 17th I saw a $1570 charge on my credit card. I called them next day, they said they never received the vehicle, the contract was still open and I was responsible for the vehicle. Also they claimed they didn't have "answering machine" so it was impossible for me to leave them voicemail, which is simply not true as their phone system has an option to leave voicemail when calling after-hours. They told me to file police report. I went to police station several times trying to file police report, but police told me Enterprise had to do it. Enterprise still hasn't filed a police report and they keep charging my credit card $53/per for for the car. They are also trying to make me liable for lost car. What should I do? I suspect Enterprise employees of that location are involved in the theft, as it wouldn't be possible to find location of the keys without listening to voicemail.
