No service - Hollard Life

My mum took out a life policy with Hollard in January this year. They started Debiting her account in January but never sent policy documents. When I called in they couldn't pick up the policy no. Which scared me. Eventually after many calls I got through a dept. That sent the policy documents. Some info was missing. They put through the policy without getting all info. I tried again but they wouldn't help. My mum had to call herself. Eventually when she did, they changed the details incorrectly. Now whoever I speak either cannot pick up the policy or just lie that they would fix this and call my mom back. No calls yet. Am I losing all my hard earned money? I have no idea what is going on. No one will help.
