Complaint Review: PCS legal dept. Advance cash USA

 Started 2 yrs ago with extremely vulgar harassment tactics at work. Threatened with being sued and losing my job. Avoiding all questions i asked. Got to the point where my boss....his boss....and the HR dept got involved, saying that continual phone calls would result in 'further actions'...or..being fired. Seems every 6 months they call and harrass while im working. So today, they started again. My boss and property manager called me in to the office. Basically im at the end of my ropes with my job. I repeatedly ask them to stop calling my place of employment and to send documentation via mail so i at least have proof. Nothing yet. I am at a lose. Not sure what to do or who to call. Lost my sons mother a yr ago and am in no position to mentally or financially deal with scam artists.
