Failing to meet their 6 to 8 weeks commitment

I made my initial withdrawal claim with AF in December last year and to date, ZERO payment has been made. I patiently and diligently with my former employer sent through everything even after the back and forth of incorrect forms being sent and debt queries being made. I've tried calling once a week without success, now I'm at my wits' end. They have failed to meet their end of the promise to process the payment within 6 to 8 weeks of initial claim and now I'm calling and begging for my money. Why? Two consultants, Mpho Motlohi and Fezekile Mvelase have since escalated the issue to their team leader Brian Setwaba, whom I'm still waiting to hear from. This is frustrating and totally unacceptable. What is a person to do in this situation.
