I am fed up, angry and hungry

I dont know what route to take now. My dad passed away in 2015. His boss had opened a funeral cover for him in his name (employer) unfortunately he passed away years before my did. My dad continued paying for the policy until he passed on, but before passing on my dad and employer wife tried to change the policy to my dad name but with no luck. Well we tried claiming since 2015 and Old Mutual asked that my mom come with the wife of the employer of which we. Did asked we provide the ID documents of the employer and wife, the employer will and final liquidation statement, an affidavit from the wife of the employer that she agrees that my mom claim the money, and my mom and dad IDs death certificate, and all the other many documents that we sent for more than once. We called up and down going to their office many times that we lost count still no help from anyone. Everytime when we follow up it is a new person we have to start from scratch. Can someone assist us what are we now supposed to do does it mean Old Mutual is ******** us? Has one of their employees already taken the money? Why do we have to be going through this? We need money we have money at old mutual that they dont want to give us Policy *** Enquiry claim ***4
