Dishonoured financial contract

I went to capitec on or around Nov 2021 to make a loan of about R249999 which is of personal nature. I have made a successful agreement with the bank and have provided the bank with my personal details and that of the bank (FNB) where my salary gets paid into. The bank have for the past five (5) months deducted the installment successfully of R7483. 66 from a 73 months contractual agreement and for no reason with no sort of arrangement the bank then decided without any sort of consultation decided to take deductions from an account which does not receive any sort of funds nor even an account that I receive my salaries into. This is ***** at the highest level, reasoning this is that in principle I have paid 6 months of installment of 73 months and the total remaining balance would have been reduced but the predicament which includes, my credit credibility, credit rating is quite important because it determines my financial status whi h is in the case of capitec is badly tarnished. Secondly, as mentioned above they decided to not honor the contractual agreement and now they have and or arw de*****ing me because there is no consultation between myself and them to change the bank where deduction should be made now they have put me back to the principal amount with arrears and now the money I have paid for the past five months has not made any sort of difference and I now owe almost the amount of R248898. 28 which is almost amounted to the principal debt of R249999 which is the amount I have borrowed from the bank. So the bank is dishonest, ************* because they have even sent my account to debt collectors without even talking to me. They made such decisions and choices and now I have a bad financial reputation because the bank dishonored our agreement and they have intentionally breached the agreement and put me in this mess and they are so quite as if nothing happened. I took the loan from capitec in Westgate mall Roodepoort branch. I am alerting people of South Africa that they must make sure, like on a very serious note because this has everything to do with your financial status that can be ruined easily by this financial institution. What really makes me mad is that they even have an audacity to instruct debt collectors to collect money which they are trying to solicite from me **********ly, because I don't understand why would have an agreement which you later breach. We have not agreed that the deduction will be made from Capitec, you make such a change and want to collect the money from me it's not a mistake at all, moreover that you even consult a collecting company try and collect arreas that you deliberately created, clearly they are fully aware of what they have done.

Please be aware of the financial institution in question because I feel there is a direct attempt to put me in this situation. I am George Chaka ***
