POOR service in trying to get payout from provident fund

I am SO disappointed in the service I have received from Old Mutual. I resigned in the beginning of February already, and have had a consultant who works for my previous company try and get my provident fund paid out to me, with no luck. I have sent numerous emails, and have had the consultant send numerous emails too, and nothing. Langley Bennett has been the contact at Old Mutual and has not been helpful at all. I have been so patient, and sent such patient emails, and to no avail. So now I am lodging a complaint. The payment was supposed to be made out by the end of April. It is 2 weeks overdue with no knowledge of when it will be sorted.
