inci,
It is not the host's responsibility to restore your files because you deleted, accidently modified or "broke" your website. It is especially not the host's responsibility to continue restoring your site multiple times because you messed up. MediaLayer uses DirectAdmin and creating a backup of your website is super easy! Literally all you have to do is press the Create Backup button when creating, and select the date to restore if you ever need to do so. Unfortunately, it seems that your incompetency is the reason why you're having issues at MediaLayer, and is no fault of their own.
