You can email us: support@fileboom.me
Also on the right side of FileBoom front page there is a widget with which you can contact us. The same widget is on the left in the center of the support, for example, on the current page. In the illustrations, we have marked the widgets with an arrow.
If you plan to write to us via the widget, then make sure to enter your email without typos, otherwise we will not be able to answer your request.
