No respons: CMPLNTS***6

I am resorting to this platform hoping I will get a response from Old Mutual. I submitted an official complaint against Old Mutual on 11 March 2022. The receipt of my complaint (with reference nr CMPLNTS***6) was acknowledged by the Complaints Handler I PF Complaints, Mr. Herold Laubsher on 14 March 2022. That was the last time I heard from Old Mutual and for that matter Mr. Laubsher. I have since requested feedback on two occasions but, to no avail. Is this how Old Mutual addresses complaints?
