How long must I wait for the death benefit payout

We lost our Mother on the 05 May 2018, she was employed under GNT (great North Transport-Tzaneen) sanlam is the service provider dealing with the employee benefits.

We submitted all the required document that were required by them. They told us is gonna take about 3 month to finalise everything. To this day we haven't heard anything from them (SANLAM). Its almost a year and half.When we contact her former employer which is GNT they keep on telling us that they still waiting for SANLAM to get back to them. Its so fustrating and no one seem to care and on the other hand we are still trying to pick up the pieces and dealing with the of our mother . Our late mom she entrusted you to do things professionally and accordingly.

FOR HOW LONG WILL YOU CONTINUE TO TREAT YOUR CUSTOMERS LIKE THIS!!!

Disappointed and fustrated Children of the late Mom
