Small dent, huge charge

Hertz charged me 289 euros for a small dent on the windshield, probably caused by a tiny little piece of rock on the highway, arguing that the whole glass would have to be replace. It’s common knowledge that small (less than half an inch) dents like this can be fixed at many different places (Carglass, Glassdrive, ExpressGlass, for example) for as little as 70 euros. It looks like Hertz took advantage of the situation since it’s clear an incident over which I had no way of avoiding it. Will not make business with them again.
