MFC Processes Debit Order as and when they want, and the Customer Service Center delivers NO Service!

Ì received a SMS stating that my debit order date will change from the 25th of every month to the 24th. My salary date is the 25th of every month as confirmed when I purchased this specific car. I called and asked that the debit order date not be changed to the 24th but remain on the 25th. After being assured that the date would not change, MFC still went ahead and changed the date to the 24th. Then this month (Sep-24) an early debit order campaign was being run. It is supposed to track your account via Debi check and once my salary is deposited, the debit order will be processed. It's the 20th of September 2024, my salary has not been paid to my account, yet MFC have processed the debit order. I phoned the call center, but it was absolutely futile. The person assisting me just gave me more and more things that I have to do in order for MFC to correctly process the debit order. How many times do I have to send documents and requests for this to be corrected. Why was the debit order date changed to the 24th after I requested that it remain on the 25th and why was a debit order processed on the 20th of September 2024 even when my salary has yet to be deposited. This is unacceptable customer service. I have 2 vehicles financed with MFC, the other account has no issues, yet this one I am just not getting satisfactory service from MFC - absolutely disgusting and unacceptable. This needs to be corrected immediately but doing it via the customer call center just means you will end up with empty promises and no actual results.
