Total silence after falsely denying claim

This company have totally failed to reply to over 12 emails (and phone calls to named personnel who Ive then emailed ) for 3 weeks concerning a claim they rejected for R63000 that having seen the policy is covered. Ive asked them repeatedly at George office and HQ to examine the situation ; and have had absolutely no response. Next has to be the Ombudsman but if youre thinking of Insuring with these people consider my experience first!
