How to protect yourself from such cases:
1. Domain and hosting must belong to you, that is, be registered in your name.
2. it is desirable that the hosting is located in the hosting company UKRAINE – https://www.ukraine.com.ua/?page=111832 – this is the best hosting company, even if you have not paid for the hosting, it does not delete the files of your site. At any time you can go to the control panel and restore or download the site. Every day it makes a backup of the site and database, that is, if something happens to the site you can always restore previous versions. And at prices they are almost the cheapest.
