Clarification on Unauthorized Debit

I am writing to raise concern regarding a debit that was processed against my account despite our agreement that I would pay only what I can afford, rather than having amounts automatically deducted. Unfortunately, this agreement was not adhered to, and an unauthorized debit was made.

I will continue to make payments via recoveries as agreed. However, I require further clarity on the recent transaction: the amount reflected as R1,988+ R999 appears to have been processed. Please provide a detailed breakdown of this discrepancy.

Thank you for your prompt attention to this matter.
