Non existing client care

Hi I've been struggling with OM Insure and Nedbank insurance since November 2024 to resolve my dual home risk cover with both institutions. They send me from pillar to post coz they want policy schedules from me since I owned the house from 2001. I've have email communications from both institutions who just don't respond to my emails or request the same information over and over again. By the way they have my policy schedules in their possession but expect me to get it from the individual insurance institutions to determine their monetary financial obligations towards me iro my premiums refundable.
