poor customer service when it comes to excess recovery

Poor service from budget insurance when it comes to excess recovery, i wasn't satisfied with the feedback i got from Bongani Radebe, telling me that the offer they received from the third party was a negative offer due to 60/40% apportionment based on law of collisions when the fault was from the third party and to make matter worse was that the amount of damage he used to calculate the amount the third party had to settle was not the correct amount of the cost of repair on my car. when my claim was finalized i was told the total damage/loss of my car is R 48729.15 but from the feedback he gave me when they get to the negative offer he noted my total damage/loss as R31035.89 which doesn't really make sense at all.
