MFC Incorrect Debit order amount

You requested for proof of insurance for my car and I have sent it on 29/08/2023 to ***. Called to check if it was received, was told debt protection cover has already been loaded on my profile but there is a cancellation request that has been loaded. Then was advised to send proof of insurance again to ***. My debit order amount is suppose to be R5137.09 and you have been debiting R5579.22 since September. I called again in November and was told an escalation has been sent, and to-date nothing is has been done to cancel this debt protection cover and the difference of all these debit orders be reversed back to me. Instead I'm receiving debicheck mandates left right and centre with the wrong amount. I am livid and want my money back!!!!!
