Sallie Mae has resorted to calling my mother's cell phone, and she gets charged for her minutes! I did not think ANY collection agency could call a cell number unless the number was given to them as a contact number! Please, make them stop!

Sallie Mae uses all kinds of tactics.  Somehow the caller got my parents phone number and tricked my dad into thinking he was my friend and my dad gave out my cell number.  Those a-holes.

they harrasme at all times. I am not even working i have to volunteer in the field and still do not have a job.

Sallie Mae is the original creditor - not a 3rd party collection agency.  

FDCPA does not apply to original creditors.

You obviously decided this was wrong but failed to do the research YOURSELF to verify it.
