Incompetence of call center stafg

I am extremely disappointed with Standard Bank Home Loans due to two unauthorized debit orders on my account within a month. Yesterday an unauthorized R3,100 was debited without. Despite assurances that my debit order would be processed on the 20th of each month, another unauthorized debit occurred yesterday. I have contacted customer support, sent multiple emails, and previously lodged a complaint via HelloPeter. However, these issues persist, leading to additional bank charges and negatively impacting my credit standing. I must emphasize that I did not authorize any deductions outside the agreed-upon date of the 20th. This situation is causing significant inconvenience and distress. I kindly request: An immediate investigation into these unauthorized transactions. Reversal of any associated bank charges incurred due to these errors and staff that is not following process as per agreement
