Poor service and no communication from Old Mutual

Our brokers transferred money into our Old Mutual Wealth investment on 12 October. A week and a half later the money is STILL not reflecting in our investment. Last week they said it will reflect this week, this week on checking why the funds are still not showing Old Mutual now say they need a form signed. Who is getting the interest on our money while it is sitting in OM's account? When you try and call them an answering machine tells you mailbox is full! We will be leaving Old Mutual as soon as possible!
