More info on disney channel audition.... please read and answer?

well anyway ppl liken me saying that i look 12- 15 so i really dont look my age, and i've been call backed before for other auditions for disney, i just didnt get chosen and they didn't even care if i had experience or not, and that was WITHOUT the agent. So even you "experts" could be wrong, because just last year i got call backed for a role. and were going to go to the agency soon to talk to them, because he said he would help me out. i auditioned for several different sitcoms, when younger Hannah Montana, Madison High, even good luck charlie and i got called back to madison high and good luck charlie but i didn't get the role, so it shows that age doesnt matter and i can go to websites where it has auditions and how i can submit it to it. but i dont want any of those. so anything else of what i could do because even some kids on disney cant even act and i know those little kids didnt go to acting school. and could i just start out as an extras to get some stuff on my resume.
