About to close my Capitec account and move to a different bank

I am super annoyed by the service i have received from capitec, in regards to my loan account, I have never ever missed one payment but capitec has left me stranded before my payday and debit order date. The issue is i took out a loan account about 2.5 years ago with a agreement and confirmation from my Employer with you guys to debit my account on my salary date which is on the 25th of each month (Please note that this is the agreement i had with capitec) all of a sudden, the passed 3 months or so have been a nightmare as you debit my account before my salary reflects within my account even if its mere R150 is left in my account which leaves me with such inconvenience. I have escalated this complaint by going to the Midrand Mall of Africa branch twice already and left with no Joy at all but frustrations to even change bank accounts for you guys not to even access my account. I have been told they cannot help me as they will debit any amount in my account from the 22nd up until the 24th which i never agreed on. So could someone please fix this issue ASAP.
