Next Car Car Rental/Priceless/RentAWreck review: No deposit refund received

So i've had a bad experience from day 1. First of all you see there are 3 company names i'm dealing with. Ultimately Next Car Rental charged my account for $661 for a car rental. I returned the vehicle on 3/16 to the San Juan, PR location and still have not received a refund! I called many times locally, corporate, to no avail. Many emails sent by corporate and no response to me personally and no resolve. I will never return to any of these 3 named companies above as they are shady. Today they told me there is an "error" in the San Juan location. With all the times I called they could have resolved this by now. Then I had to file a dispute with my bank in the fraud department to dispute the transaction. Bottom line is I need my money back!
