No payments after my mother's death

I lost my mother on the 20th October 2017, she had policies with OLD Mutual. I went to old mutual to claim twice. first time it was for funeral and second time was life cove and green light whatever, mind you I took 2 weeks leave to prefer and do all my mother's claims, and when I left plk branch they told me that all is in order till I got a call from OISA from head office they want outstanding documents which made me furious and he said the is a form I need to fill he will urgently sent it and leave plk branch alone hence they could help me he will assist till today I am still waiting for the form, last week a lady called Nicolet said she will assist till today, I spoke to some lady today and I told her that im sick and tired to be taken from one pillar to post they cant service their costumers like that it is a total disrespect, now those assisted me with funeral money I cant pay them back because of this stupid insurance, may you kindly assist im in hospital as im stressed of my mother's death and this depressing old mutual CEB ********** 60 MY MOTHER *****goa cecialia mahlaela ********** 256083
