Disrespectful behaviour towards deceaced family

My father was a loyal client to Mutual & Federal through Vaalrivier Makelaars as broker for many decades. My father recently passed away. His yearly insurance payment was due 1 September 2015. Vaalrivier M. provided me with incorrect information saying the policy was for ''house content'' for R2.5 million insurance. I communicated with Vaalrivier that there is no way that my parents household content is worth R2,5 million. From then on they refused to be helpful. In fact the policy is for house buildings. <br> <br> I informed them that my husband is the executor of my father's estate and can legally act on his estate's behalf. Instead of treating me like a valued client they started treating me like an adolescent and refused to communicate with me. Despite instructions from me to include me/my husband in communication they ignored me and only talked with my attorney. I was the person responsible to pay this Mutual and Federal Policy since my father's estate is frozen with his death. Vaalrivier M went out of their way to make a difficult time (my father's death) more difficult by (1) not knowing or bothering to know the contents of the M&F policy (2) complete disrespect towards me
