Very disappointed

I am very disappointed at King Price. My vehicle was in an accident for which my claim was approved and they took the car to their chosen mechanic. However the mechanic did a poor job on the car using very poor quality parts to repair my car. The workshop did not even bother to wash the car before returning it to me. After driving my car for a while, the park assist sensors started to malfunction. I took the car to Toyota and they said the wiring was done badly. I sent Mr Aldon Wait an email as he was the one handling my claims requesting a refund for the work Toyota did to fix the incomplete work done by their panel beater. My emails were never responded to, I even sent photos as provided by Toyota. I received no feedback at all, I even resent email following up and still I received to response. Last week I decided to follow up with the call center and the lady assisting me told me that the matter was settled and a report was written by the panel beaters. My question to King Price is how is a report written without proper investigation? I asked them to hire someone close to me to inspect the car and write a report to compare with what Toyota said but they did not. No one inspected the car, no one contacted to Toyota for the report, no one contacted me to ask any questions but my refund was denied. I am very disappointed in King Price, after the way they handled my case I am considering cancelling my insurance with them.
