No car but my account is still being debited.

I took a Renault Kwid 1.0 Dynamic with the company with hopes of using it for the purpose of e-hailing services, everything was going until about 2 weeks ago when all of a sudden the vehicle just stopped and refused to start up again on the N2, I contact the company and I was informed that someone would come and assist with towing the vehicle to East Point Rentals premises. As per agreement the lady I spoke with confirmed that they would stop debiting my account as the car is out of business and the is no payment coming in for me to make the weekly repayments but funny enough that same week my account was debited, I then enquired and was informed that that a mistake happened and that they would be giving me the money back and stop the debits on my account until the car is fully operational again. This is the 4th time my account is being debited now with them telling me the same story over and over again. When I went to bank branch to try and get the debit order stopped they told me that they have stopped it but can't promise anything at the company (East Point Rentals) keeps on changing reference number. This absurd and completely ***********. How do you guys expect me to continue with business with you guys if I still wanted to once the car is working again? You are total *******s with no honesty. I need my money paid back into my account as you are debiting me for a car that is with you guys.
