Pathetic service and empty promises

I was given a turn around time from old mutual superfund pension fund department of 20 working days to pay out my claim. It is now almost 30 days and I have no pay out. I am the only client in the entire country who's claim was rejected due to some system error that neither management or their IT department can resolve. I am frustrated as I am now two months behind in my car and bond payments due to old mutual lack of service. Pathetic is an understatement. I call everyday and spend almost an hour just holding for someone to answer my call. I want my money immediately. This is unacceptable.
