Old Mutual Life Policy not paying out after a year and 7 months

Its been 1year and 7months since the passing of my father....to date after multiple attempts via email and phone calls Old Mutual has not paid out my father's life policy, which was paid by him for the sole purpose of assisting my mother financially should anything ever happen to him. Our financial advirsor as well as my mother who is a pensioner has tried via phone calls and email to get Old Mutual to pay out what is rightfully owed to my mother. The incompetence of such an 'established' company is unacceptable. The public needs to consider this before considering to invest at this establishment as we have had no feedback or ANY assistance. The emotional toll this process has taken on my retired mother who lost her husband is so unneccesary and I am peturbed to say the least. Totally unprofessional and unacceptable for a company as Old Mutual!!
