Extremely POOR and VERY bad service from SANTAM/SANLAM

I have been struggling for months to get a Third party insurance claim paid out to me. My car was bumped into while stationary and without anyone in it, safely parked and the insured person registered a claim to have my vehicle repaired. It's been MONTHS with NO joy at all. Not even the managers I contacted are willing to help me. SANTAM wants to pay only half of the damages??? This is the WORST service EVER!!!!!!!!!!!!
