Old Mutual causing financial hardship after death

My family is now struggling for 3 months since my father’s passing to get Old Mutual to pay his death benefits and to transfer his Living Annuity to another company. How do they expect my mother to financially survive and to pay all the expenses? They have no interest in finalizing claims and will send you from the one department to the next. Families take their insurance death cover thinking they’ll be financially ok after a breadwinners death, just to experience this.
