No feedback from MBD/Direct Axis once debt is paid in full

I have been struggling since 17 April 2025 to get a letter from someone at MBD/Direct Axis confirming I have settled the outstanding amount. I have sent numerous emails to Faith Khanyi Customer Care Consultant ( Email *** ) and to date she has not responded. I need evidence that the account is paid in full URGENTLY but it seems once they receive their money they are not worried about anything. Hoping someone from MBD/Direct Axis will see this and assist me.
