Unhappy Santam customer - No recovery of claim costs done as yet

In October 2025, I had a claim where I was filling fuel at the petrol station and the attendant forgot to take out the petrol pump. I have driven off and the pump detached from the main station damaging the back of my car and the windscreen. My vehicle has since been repaired, now it was time for Santam to recover the amount. Whilst you would think it is the normal process for the claims to transfer this to their Third Party Liability department, that was no the case. I had to call them and tell them to please recover the claim costs. They requested for the contact number for the petrol station and they tried contacting the owner and that was it. They have made no attempts after that. The last email was that I needed to to contact the owner of the petrol station. I do not get any feedback unless I ask the person at Santam for it. What happened to Subrogation, where I subrogated my rights to the Insurance Company when a policy is taken? Please can somebody attend to this urgently as I need my excess paid back to me and the total recovery done
