Dishonest and Unfair

My vehicle started OVERHEATING on the 20/12/2022, I stopped using it and had it towed to Audi. An assessment was done by a technician and a report submitted to Motorvaps, of which over 90% of the claim was disputed based on the assumption they had NOT the assessment report which said the opposite of what they're disputing. My vehicle hasn't missed a service at an RMI accredited workshop and as per instruction (1 year/???km). I have used 3 different RMI approved workshops on my vehicle, including Audi, and have the service records, in all my services, no issue of wear & tear was raised to alarm me. Of the +R17130 quoted, OVERHEATING is covered for R15000, meaning, subtracting the 10% (excess) I am liable to pay R2130. However, Motorvaps have tried to duck & dive, and not honour the claim by saying they'll only pay R1162.
