Disappointing service and process flow

It has been over a month and there has not been any feedback from momentum in regards to my provident fund withdrawal. I have tried calling but calls get disconnected, I have requested to be contacted on all social media platforms and still nothing. What kind of service is this from such a huge organization? I'm very upset at the service I am receiving from momentum at this point. I feel Hilgard “Hillie” Meyer(CEO of momentum) should be hands on now as there’s a large number of clients who are experiencing this horrible service from a huge organization. Contact me on ***
