ACCOUNT DEDUCTED WITHOUT CONSENT

I have four accounts with Absa Bank. I have been a loyal customer for a very very long time. I have missed a payment and has been trying to make arrangements to pay the outstanding. I have mentioned to all consultants that has made contacted that i please need to arrange for an additional month to be added because i'm not able to pay R1700 x 2. I received another call on Saturday from SHIREEN at absa and not long after the phone call my SAVINGS ACCOUNT WAS DEBITED. All the years of paying my Personal Loan this was debited from my CHEQUE ACCOUNT. My savings account was opened this year 2016. The debit which took place was taken from my SAVINGS ACCOUNT AND NOT EVEN MY CHEQUE ACCOUNT. I would like someone to get back to me asap. This is ********* behavior from a bank that i have been with for many years.
