A website has “stolen” my program and reselling it

Hi the website https://www.ektor.io has stolen my entire program https://github.com/instabotai/instabotai/. He is breaking both my old license and my new. He does not credit me or the repo in any place and he has just excluded the license from my program which he sells for $49.

What can i do about this ? I am thinking contacting his host today.

Thanks
