No feedback for the deceased claim

I submitted all the documents for the death claim of my mother on the 11th of August and was told i will get feedback within 15 days, that never happened, when i contacted them, they told me they need more time, i will get feedback in 10 days' time, that was the 8th of September, and to date no feedback, i emailed on the 30th of Sep and no response, i called yesterday and still no feedback. This is really frustrating, any response is better than no response at all. if they are not going to payout my mother's pension they must say so, so we can all forget about each other and move on. I'm very disappointed at the way OM handles things, i am definitely looking at cancelling my own policies with them, i cannot have my family suffer like this after I die, NO.
