Bad service and unpaid claims!

I am so disgusted and disappointed about the service or no service at all by Old Mutual, it has been over Six months since my Father and i have claimed on my late mother's investment and has no yet paid out, when we re visit the branch which we have done more than 10x,they always give us excuses that the head office is not processing the claim or asking for more documents of which they where all submitted, no communication with us what so ever, my father is mourning and still has to travel back and forth from Limpopo to Benoni just to go to the Branch in Benoni Lakeside mall and ask for an update himself and the answer is still the same we are on top of it ,we will be depositing the funds in a few days, still nothing! i am sick and tired of Old mutual and everyone in my family is thinking of cancelling their policies as they are unreliable at a time of need!
