Unfair treatment after Successful claim

After one successful claim MiWay increased my premiums and I kept quite.

And on the 22 of January, the head of claims sent me an email threatening on canceling my insurance, or increase the access fee, or premiums "again" if I do not improve the so called "my profile". My goodness me, did I chose to have an incident? And who was responsible for quoting me so cheap as now they consider it to be an issue? And who chose the car dealer who fixed my car since now my claims are above what they anticipated?

It is obvious that the Insurer only car about the profit, and not the wellbeing of their clients.
