Is franzis.de Safe?

Some time ago I have applied for a free aka giveaway software license from them and since then I am receiving a lot of SPAM. The unsubscribe link does not work because the next day I am spammed againg. I did contact them thru their website and did not received any answers. That makes ***** spammers, scammers, unethical and a high privacy risk website. End of story!
