Failed insurance claim

In 2025 21st of October,Santa client collided with me and damaged my vehicle authentic back ,he admitted that it was his fault and he will claim a third-party at his insurance being santam,santam contacted me and I submitted all relevant paperwork from me that they request and made me not to claim in my insurance and they even treated me like I was the one who caused the accident while their client is the one because he failed to stop at the stop sign,Till to date santam has never said anything and I'm driving a damaged vehicle and when I try to call them all they do is to transfer my calls and no one pick up...I would never recommend this insurance to anyone I care about
