Failed hosting migration- is my website safe?

Hello.

I joined FreeHost with the domain yanivgonen.ezyro.com.
I also have a website with the domain yanivgonen.tk under the host server Hostinger.
Since my Hostinger subscription expires at 23.9, I tried to migrate its website to FreeHost (to the domain yanivgonen.ezyro.com), but unsuccessfully.

What I did instead, is using a backup files of the source site, and uploaded them to the destiny site, via WordPress.

That caused one giant mess- the domain yanivgonen.ezyro.com directs to yanivgonen.tk, and I have no idea which host they belong to.

All I want is to make sure my site is here on FreeHost, safe, and still works when my Hostinger subscription expires later this month.

Thank you
