Poor administration and service delivery

I am financed with marquis finance and the administration of this finance company is disorganised. At time i think they do it intentionally.

I purchased my vehicle in 2022, my debit order date is the 25th and I had never missed a payment. In December 2024, they did not debit my account. When I noticed on the 29th that they had stilled not debited. I tried to contact them without success. It came to the end of the month and still my December in installment was not debited.

I waited and left the money in the my account hoping that they will call, or double debit me in the month of January 2025. But they never did!! Calling them was not successful so I just waited them to call me since I cannot reach them. THEY NEVER DID! then suddenly, I received a double debit in the month of March. Without any warning whatsoever, I requested to make an arrangement of R1000 extra over and above my normal installment, they agreed. However they only did that for one month, the following they did not. I do not know what else to do anymore.
