Financial questions that need an answer

what could you do if u knew someone’s SS# but dont know their full name?i want to get someone back for f*cking my credit up.but im going to only use 300 of their dollars.im not going to be so mean but i know for sho that this surely will teach him a lesson.anyways i saw some cute shoes online.could i get them with his social security number.OR what could i get?how could i get more information for free?

im not a bad person.its just this mortal really f*cked my credit up.and now i cant even buy another new car year 2009 jank that i wanted.i have to spend at least 2 years paying it off.but he aint got the bread like i do so me spending a lil 300 dollars would kind of be alot to his cheap a*s.
