No service despite several attempts

We've tried to settle my vehicle for the past 6 weeks. All payments have been made by myself and my insurer but Absa failed to allocate all of the payments appropriately and as a result I have to keep paying for a vehicle that has been settled. I've spoken to several agents, all who were unable to help me and who referred me to the claims department. None of the 6 provided numbers for the claims department has ever been answered.
