No payment in 7 months

My father passes away in February 2015. Since then to date there has been no payout of the pension or death benefit. My step mother whom my father was married to had to take on all the debts and didn't have a job since then my sister and myself have been paying for all the debts. I feel it's exceptional poor service that after 7 months there has been no payout and no one at the call centre can tell us when it will pay. We have spoken to numerous people at the call centre and social welfare from the mine as my father used to work for Anglo American Platinum but to no avail. This is a trying time for the family and expected Old Mutual to respect this.
