I resigned from my employer in March and from 10th April I have been trying to cash out my pension fund

I resigned from my employer in March and from 10th April I have been trying to cash out my pension fund. First Momentum cashed out my savings portfolio which I did not ask for then it took them 3 weeks to reverse after back and forth calls which ended with me screaming at their consultants. After that was resolved I was promised that I would be paid last week the senior agent I have been dealing with is now ignoring me. I called 5 times this morning Katlego and another consultant hung up on me. Then another promised to pass the message on since Kevin doesn’t take calls. I have been battling with money that I have worked for over 17yrs. My debit orders have come back unpaid yet I have money sitting in someone’s account. The excruciating pain I have had from Momentum is beyond shocking. Lack of empathy from the consultants as for Katlego a **** of note from day one. They don’t respond to emails I’m at my wits end with this company.
