Folks, I've found something 
I'm not sure whether it works or not, but it allows you to submit support ticket, sooo I figured it may be worth giving a try. Oh, also I used Hamachi, so idk if this option is available in other products.
I went to Hamachi support (https://support.logmeininc.com/hamachi), then typed Delete account in the box and chose the first question (it should probably work with any question). Underneath the anwer there should be three options: Ask our Community, Call support and Open ticket. When you choose the last one you will be able to pick Account as a subject. All you have to do now is describe your request and send it.
I think that should work good luck
