Volkswagen of Union VW has not paid off my trade in! Union New Jersey

I purchased a VW Atlas and traded in my Ford Explorer on November 17, 2017.  I was told that the Ford would be paid off within 30 days.  As of today, January 19, 2018, they still have not paid off my car.  I had to make two extra car payments and incurred  a late fee.  I am now nearing my third payment for a car I no longer have in my possession.  

I have called the dealership numerous times and have had no responses.  I was given multiple voicemails and told to leave a message.  I received a call back five days later only to be told that the accounting department was closed and that they didn't have any answers for me.  

I then called cooperate and they really haven't done much to help.  They have just taken my complaint.  VW refuses to get back to me and will not give me a payoff date.  

I then had Ford Credit call the VW dealership last night and spoke with Carlos Inoa. He promised me that I would have an answer by 12:00 today.  They still have not called me back.  I called again today and was just given a voicemail. It is now 7:00pm and still no response.  

No one is helping me with my situation and I'm extremely frustrated and dissatisfied with how this situation is being handled.  All I want is for the car that I traded in to be paid off like the contract says. The management is deceitful and unfair.  I had to make extra car payments through the holidays.  In addition, I spoke to a VW of Union rep who stated that they are getting numerous complaints about the same issue. Bottom line is once you purchase a vehicle there, management wants nothing to do with you.
