Accidentally Licensed - big headache

Hi, I`ve been using Adobe stock for a while and NEVER had any problem, but I was working with a friend at home and I said to him to take a look on Adobe stock to find something interesting that we could use on our project.  I had 43 Licenses avaiable and when I got back from shower, YES he lincesed all of them, ALL OF THEM at once (seriously) his fault yes, but not inttentionaly, he thought that he was just putting on a "favorite list" something like that.
Is there a way to "unlicense" them ? At least some of them ? Send back, I don`t know something..
