Business ProfileforMurdock Hyundai of Murray

I bought a brand-new vehicle from this dealership on July 29 of 2023, and I was advised that the loan was approved and financed through Hyundai finance and my first payment was going to be on September 12th of 2023. On August 16 the vehicle broke down and left me on the side of the road in the State of Idaho having to get a towing truck and spend the night at a hotel. I had to have my wife drove all the way to Idaho from Salt Lake City UT to pick me up and bring me back to Utah, the dealership did not take any responsibility for the cost of hotel, gas for my wife's car and time lost from work for me and my wife. The dealership gave me a loaner vehicle while they fixed my vehicle. This took about 2 weeks to get fixed and get my vehicle back. The dealership made me signed a new purchase agreement were my first payment supposed to be on November 9th of 2023 at a 1% interest rate lower than the original purchase agreement. On October 27th of 2023 I received a Text message from (Preston) from Murdock Hyundai stating that they still have not finalized the financing of my car loan and I have to pay the dealership a payment in the amount of $1,898.32, I advised them that they made me signed a new purchase agreement with first payment being on November 9th of 2023 in the amount of $949.16. I went into the dealership to speak with them, and they told me that they are acting on behalf of Hyundai financing and if not, payment received they will send me to collections. In order to not be reported negatively on my credit report, I was forced to sign a promissory note stating I would make payments to total $1,898.32 spread out in to 6 months. I feel the dealership are harassing me and threating me to be sent to collections if I don't pay them the total amount of $1,898.32 which is the opposite of what a fully executed purchase agreement states. I need assistance forcing what the signed agreement stipulates and not be forced to pay an amount they want disregarding agreed upon terms
