Not getting my monies worth

I took a policy with Unity insurance on the 25 May 2017. After 5 months of paying and thinking I'll be able to claim I was given stories. My car went in for service on the 04/12/2017 at VW , the technician working on my car picked a few things and after finally getting through to Unity he was told that they'd only pay R3000 of approximately 6 or 7 thousand rand. I was rather surprised because according to the policy schedule each component is covered for a different amount and the only one covered for R1000 is the entertainment system, the other two components could be in the 2-3 thousand rand ranges each, but my claim would only cover R3000. Can companies stop being dishonest to get business, I know you are about making money but what about your brand???
