NMG - WHERE IS MY MONEY????

I am extremely disappointed in NMGs service. My provident fund claim was submitted in August and up until now no payment has been made. I was given a timeline of 6weeks to be paid my benefits which has passed. Nothing has been communicated to me as to why the benefits haven't been paid. Furthermore, calls are being cut when i am trying to call and follow up. I am getting the same email reply over and over-a reply that is not helping me with my claim. I feel like I am literally chasing NMG for my benefits and I am frustrated. If I could go to their offices personally-at this point I literally would because this emailing and calling is not getting me any proper responses. NMG surely you can do better than this???
