Method File::deleteDirectory leaves some subdirectories non deleted

In my laravel 5.8 app in envoy task I delete old derectories with method :

use Illuminate\Support\Facades\File;
   ...

   File::deleteDirectory($directory_name);

But opening server's dirs are see that directories are not delete, but have some subdirectories inside. When the 1 directory is not deleted, like removing directory

/var/www/html/Hostels2Deployed/release/20190725-191130 

I found it with 1 subdirectory

/var/www/html/Hostels2Deployed/release/20190725-191130/storage/framework/cache/data# ls -la
total 16
drwxrwxrwx 4 lardeployer www-data 4096 Sep 27 11:59 .
drwxrwxrwx 3 lardeployer www-data 4096 Sep 27 11:59 ..
drwxr-xr-x 3 www-data    www-data 4096 Jul 25 16:12 cb
drwxr-xr-x 3 www-data    www-data 4096 Jul 25 16:12 ed

Why they are not deleted and how to delete it?

Thanks!
