Worse customer service and Bad accounts management

I will never trust Direct Axis loan or do business with the again. I missed R1500 debit order in November and made an arrangement to collect in December and January. December R780 arrears collected. January called them to change debit order banking details and they only collected normal instalment and now I owe R2000 which Direct axis is failing to explain how it was calculated. I called them last week and provided all bank statement to investigate even now I am still waiting for feedback. When you call the call Centre they drop the calls or put you on mute and don’t even call back. Please investigate Direct axis loan and Sanlam Direct loan after request someone who knows, understand accounts and can make informed decision to call me
