When I try to contact mojang, it says it is a spam

So I tried contacting mojang before (on december 20th) but they would not reply to my case, so I tried to email them again today and the it says "the systems thinks this is a spam. Fill out the captcha and try again" yet there is no captcha to fill out anywhere. Could I get some help please? My account got stolen and I can not get it back.
