Dissapointed in Santam insurance

My motorbike is fully insured by Santam. It was ****** in September. They used screenshots of used and broken motorbikes of a smaller type than mine that they got off a second hand selling site and used it as some kind of proof to only pay out 17% of the insured amount. They also have very bad service and reponce time. I expected much more from them and I am very dissapointed. Still awaiting responce from them to clear this matter out. Thinking of switching insurers.
