3RD Party Claim Complaint

On the 26th July 2015 I took my wife and kids to the Sonneike Shopping Mall in Kuils River. My wife's car, a 2014 Ford Fiesta, was parked at the parking are. When we came out of the Mall the car was badly damaged and hit by a BMW in front. Luckily the owner of the vehicle didnt run, called the cops and all necessities done. We decided to go for a 3rd party claim through his insurance which is Santam. The claim was registered on the 29th July 2015. We submitted a repair quite from Danmar Autobody Cape Town which assessed the repairs to be approximately R83000. It took them more than 2 week to finally come back to us with an offer from their assessment.<br> <br> They have come back to us and said the car is a write off. They are valuing the car at Retail Value = R150000, and Trade Value = R136000. They are taking the mean of the 2 values which means a value of R142000. They are also saying the salvage amount = R70000 (as they say we have to keep the car). Basically they are offering us R72000 cash which is way too low than the repair value.<br> <br> Not sure what to do now.<br>
