Island Auto Mall

I have tried contacting this company more than four times since I purchased a car in late March. They have neglected to get a hold of me and send me any type of paperwork. I have already made two payments toward my new car for the months of April and May. My other car which was a trade-in, was sold to them and they are still charging me for the old loan payment, being taken out of my bank every month. The contract clearly states that they paid off that loan for my 2013 Hyundai Elantra. After getting a hold of a customer service representative, twice of the four times I've had contact, I was told they would call me back by the end of the day and they never have. I'm seriously concerned at this point given all of my efforts and nothing in return. I bought a $40,000 vehicle and they haven't reached out to me since the day I left the lot.
