No Reply to Calls

We have an insurance claim that we would like to register. We have been calling since Monday on your business claims line. Been on hold for hours. Have left a detailed message with contact contact details. Alas, no reply. Furthermore we have issued complaints on social media which has been received but not rep**** to four days after the storm damage at our business. The business can't operate until Fnb gets back to us. Safety and security is being breached by the lack of service.
