Shameless treatment of the family of the dead and dying

On notifying discovery of the death of my parents (within a month of one other) they immediately suspended their discovery membership, but did so based on my father's death (the main member) which was almost four weeks prior to my mother's passing. She was terminally ill and had an oncology benefit as well as an Advanced Illness Benefit. Now Discovery is refusing to pay the health providers for my mother's claims that occurred subsequent to my father's passing, because the membership was suspended. Prior to his death I had third party consent on their membership. but that fell away on my father's death and now Discovery refuses to talk to me until I get my letter of executorship (the Master's Office of the Supreme Court is very tardy and I am told it will take months). Furthermore they went so far as to refunded the October medical aid premium to his bank account, effectively leaving my mother with no medical aid cover in her last few weeks of life. Not only am I mourning the death of both my parents, but I am being stonewalled by a heartless and unsympathetic Discovery who refuse point blank to even talk to me about the issues. Wow!
