Unhappy with information I received

Good day, I am currently having financial issues but I am still trying to pay towards my outstanding credit by making direct payment into my active Capitec banking account. For some reason I received a final notice and when I contacted their offices, I was advised that it was because a new arrangement had to be made. I don't have a problem with making the arrangement but I don't want Capitec to access my new banking account because they might go in and change the amount. I advised the consultant that I will make payment into the Capitec account for them to collect but I was advised that I cannot make this kind of arrangement after I have been paying this way for the last few months. My ID number is *** in case someone else wants to assist me, because it seems like they clearly want to list a judgement against me on ITC even though I want to pay.

ARREARS NOTICE: In spite of numerous attempts, we are unable to make telephonic contact with you. Please note that the arrear amount of 36891.19 on your credit account number *** remains unpaid and you are requested to make an urgent payment to correct this.
