Poor service and incompetence of fnb momentum staff

Been trying to contact momentum for feedback, advising progress on withdrawal of my unclaimed pension fund. Sent all relevant documents 2 weeks ago but still have not heard a word from them. Everytime I call they make me hold more than 5 minutes before they answer, and when they do, they transfer me to another extension where nobody ever answers. They make me hold for another 20-25 minutes until my airtime finishes. Managed to get hold of the managers direct number, Stephen Waterston, but he too never answers the phone. Sent him an email 3 days ago but still have not received response from him. The service there is poorly managed. All I ever wanted was feedback, advising progress on my request.
