I purchased a vehicle and traded in my vehicle on May 9 2024 . Received a phone call on Jun 3rd 2024 from the dealer's finance manager (*********************) which I also dealt with during the purchase. and he said the finance isn't approved by the loaner and I needed to come in to get another contract filled out which I replied by saying that that's false, the finance was secured by the dealer through **** of America and **** of America already sent me my account detail with the 1st payment due date. He then went on to say that they won't be paying the remaining balance on my trade in. I asked him what he is talking about since I already got a letter from my bank stating that the car loan is now paid in full and the account is closed. That's when he decided to tell me why he really called and said he made a mistake on the amount he put in for the trade in amount and accounting caught it and that I would have to come in to sign a new contract either to add the amount to the financed amount or pay it in full. Then I told him I would need an email sent to me with the section that the mistake is highlighted and where in the contract agreement says that we can change anything after it was signed. He then went on saying that we can do this the easy way or the hard way and some other threats which I ignored. He texted me on my personal phone then after with threats. Now I came to find out that he put a stop to the necessary paper work that needs to be sent to the ********** of ******* to have the temporary registration removed and have an actual registration and title so I can have a tag for the vehicle. I called the dealership to see what can be done and I was told that he is the one who is responsible for it. I contacted him after to tell him what he is doing is illegal since they only have 30 days to file everything which I got a reply back that said, I should keep in mind that I am dealing with a billionaire owner and that the conversation is over.
