Debit order hassle

Hi.i bought a car in October 2021 and I am being financed by standard bank.ever since I have never received a statement ,they have have never debited their money as per agreement. I always have to make cash payments and ask again if they have received a payment. They never send any acknowledgement of payment.they dont communicate with me at all.instead they keep telling me that they are sorry every month and that the matter will be resolved but everytime when I call them they say there is nothing on the system that says i have requested them to debit their money.i am worried that they are giving me bad financial record and I now dont have a clue on what I should do to solve my problem.
