HIS database

Hello, since my car insurance has cancelled me because of too high damage frequency I was probably included in the HIS database. First for all who do not know what HIS is:http://…che-versicherungsboerse.de/…/index_dvb.php?… After 5 years you should be deleted from HIS if there is no new reason for an entry. From when do the 5 years count? On the day of the damage which led to the termination? Or other date? What if I now marry, take the surname of my girlfriend Is it right that an insurance must inform me if I have been notified to HIS? How do other insurance companies rate such data? If I want to switch to another car insurance company in 3 years, for example? Greetings Frank
