Denying policies including life cover despite proof of deduction

My aunt died after years of paying hollard 3 policies including a life cover, now local offices and head office cannot trace any policy on her name after numerous calls and office visits with proof of deduction for 3 policies. This the worst service especially when a family is going through such a time and a bread winner who thought was making sure her family will be taken care of leaves behind denied policies despite proof of her paying her dues
