Help with this website: http://www.radiolaotra.tk

Good morning, some time ago I asked a friend to make a page to broadcast music in streaming during the day and had as a website http://www.radiolaotra.tk, I want to make some changes within the page and I can not do it, now That this person who created it I can no longer locate it and has not given me any input to the control panel that I can do to be able to enter and make the changes since I do it under oath that the page is mine.
My name is Ismael Fernadez Cavero this is my email ifernandezcavero@hotmail.com and I am from Peru and the person who created the page is called Yuri Flores
