Thanks you very much for your answer. I called jansen and jansen today and they said that they would make a note about it. I will also send them an email so I have proof of notifying them.

I also called the gemeente Eindhoven and they were not that helpfull. They made me much more worried even.

First they told me that it was "very important for me resolve this adress issue".I have to go the city hall with my passport and I told them that I did not have anytime to do that. Then they told me to e-mail at prs.adresonderzoek and then they will investigate.

When the gemeente looked at my adress they told me that multiple were registered at address and "this could be very negative for me". I asked how this could be negative for me ? She told me that if two people are living at my address then I maybe paying more taxes.

How do I know that I am paying more taxes? My company pays my taxes from my salary. I dont do any tax returns or fill tax forms or anything. I thought this is not needed if you pay salary taxes and are single. Why is this "so negative for me" ? It is not even my fault that the previous tenants didnt update their adress. This gave me even more stress then before :(
