Using someone else's trademark on the site?

Question

Law in IT

Good afternoon!
The situation is this: there is a company that uses (including on its website) a registered trademark of our company.
There were no answers to our letters about the removal of this very sign from the site, the sign was not removed (although there is a decision of the Federal Antimonopoly Service in our favor).
Kind people advised me to apply directly to the organization that provides hosting for this site, sending them all the papers.
Question: how to find out who provides hosting services? Also, has anyone had any experience with this kind of situation? Share your advice, please.
Thank you in advance to all who respond!

Answer 1

The easiest would be to break through the site through any whois service ( for example ) and look at the registrar and ns-server.
Surely there is no other way to contact that company other than by writing letters? Isn't there a phone?

Answer 2

Why not just go to court?

Answer 3

If there is already a court decision, then work with the bailiffs. There, too, a certain time is given for the court order to be executed, contact them.

Answer 4

How is your trademark used? To make a profit or just indicate that that company works with you as a partner?

Answer 5

You can try to find hosting by DNS domain.
