Business ProfileforCarfect

I have an auto loan through Carfect for my 2015 ****** Altima. My payments are $250 every other Friday. On July 5th, I called Carfect to let them know I would be making my payment a few days late. My account rep ******* offered me a promo to push that payment to the back of my loan saving me from the fees and negative mark, all I needed to do was send a copy of my pay stub and sign a form. I agreed. I sent the stub that same day and just needed to wait for the form to sign. It never came so I called and ****** finally sent them on 7/11/24. I signed immediately and sent them back. I thought I was good to go. My next payment came due on 7:19 and I needed to catch up, I was unable to make a payment online and thought my payment was taken out and it wasnt. In this time frame, another payment came due, making me past due $500. Cool, I called to set up an arrangement and collected the money by the day I said I would, around 8/9/24. I called and called and called and could not get through to a person. I left a voicemail, I emailed ******* I called whatever number I could find online and I was unable to find anyone to take my payment. I finally gave up for the night figuring Id get a hold of someone the next day. I was wrong. I have now been calling and emailing every single day trying to make my payment and no one will take it. They keep telling me either ****** is out of the office or will call me back and he never does. I requested a supervisor and no one has called. I finally spoke to someone and she said only ****** can take my payment and a supervisor would take ***** hours to get back to me. In the midst of all of this, since the promo was never put through, I received a repossession letter saying I was a month past due. According to my calculations I should only be 2 weeks since I qualified for the promo but ****** never completed it so not only am I out for repo, I have fees, cant get anyone to take my payment AND Im taking the negative mark to my credit.
