Treatment of staff issues

In october 2017 i submitted a claim for my provident fund to be paid out it is now 6 months later and still we are beign given the run around. When we phone lewis head office the lady is always not at her desk or unavailable or off sick. When we phone alexander forbes we get told they dont have the approval from lewis to process the claim. I just phoned head office again and was treated very aggressively when i asked when she will be in and i need assistance as this has been going on for six months and the lady told me "listen i caught this call and it is not my problem dont make your problem mine." i seriously need some help as this has been goung on for 6 mobths and i am desperatelly waitng for my money to be paid out that was very easily taken off my salary every month.
