Old Mutual Complaints Manager no Feedback

I previously posted in connection with Old Mutual refusal to pay out on a life insurance claim. I, 64 year old pensioner, had a life insurance policy on my mother in law who recently passed away at the age of 87 years old. When I contacted Old Mutual to claim they said that the policy was for me and my mother in law was the beneficiary. I have been with Old Mutual for 35 years and feel terribly de*****ed. I posted on hello Peter, the complaints manager Belinda Hunt said she would investigate and get back to me and I have yet to hear from her or anyone else from Old Mutual. All I would like is the telephone transcript whereby I app**** for the policy through the Group Life section call centre. I am very disappointed in Old Mutual and its service.
