Deceased estate frustrations

We have been running back and forth on my mothers estate since May last year at Signet mall dealing with Mr Yantjies and we are still not getting assistance. Losing a loved one is enough weight to carry, can we get assistance please!

In our last visit he promised to get back to us and I insisted he writes it down,didnt and the call never happened.Yesterday we go back and in his absence we were told only he can assist as the system does not guide them much. Can someone else take over now please.
