double debit equalling almost my entire salary

<p>Nedbank has double debited my account regardless of the fact that i had told them on 08/12/2016 that i will pay this months installment in full and make further arrangements fo the arrears.i was not informed that there will be a double debit and Mpho who is a team leader in collections didnt seems to care about my other living expenses even though i advised them that its almost my entire salary...THIS IS BAD SERVICE WHEN IVE NEVER BEEN IN ARREARS SINCE INCEPTION OF LOAN MORE THAN 6 YEARS BACK.NEDBANK DOENT CARE ABOUT ITS CUSTOMERS</p>
