No acknowledged

I have submitted my complaint in writing to the NCR on 27 August 2025. I followed up on 03 September 2025, as I received no acknowledgement and was advised by the consultant that the turnaround time was 9 days for an acknowledgement or response. The turnaround time has lapsed, and I have yet to receive an acknowledgement. What is the point in lodging a complaint against the conduct of a credit provider if the complaint is not managed.
