On XX/XX/2015 Security Finance XXXX sent out XXXX their representatives to my home to give me a message to call the XXXX branch.  The representative went to my apartment my daughter (a XXXX year old) answered the door.  The representative asked for me my daughter told her that I was at work.  Instead of asking for the babysitter she questions my XXXX year about where I work.  My daughter told her at the office.   She says ok thank you and walks away.   She comes over to the office says I'm from security finance(wouldn't tell me her name).  I tell her you can not harass me at my job.   And that I received a letter in the mail.  I will call them later.  I asked her to leave my job she was on the phone with the XXXX office. She was telling the XXXX office she is the XXXX (XXXX).  She had the phone on the speaker phone she kept telling me to talk to the lady on the phone.  I told her to leave out the office.   She left stood outside the door with the phone still on the speaker phone.  She was talking very loud.  Residents that were in the XXXX (located right next to the office) later told me that they could hear her saying "yes she works here what do you want me do do"?  She comes back in the office while I'm on the phone trying to do my job.  And tells the lady on phone "she is on the phone now I will wait here till she gets off the phone".  She goes back out the office come back in by now I am so embarrassed that this is happening at my job.  My personal business is being handled on company time which is a violation (so I was played on probation).   I asked her several times to leave.  She just kept getting louder and louder standing there with the phone on the speaker phone telling me you owe security finance you need to pay it.  People  outside the office could hear her and people in the back of the office could hear her.  I called my boss to ask her to help me get her off the property she was not on the property and told me to call the police.  That's when the lady goes and stand in the door and yells you need to call the XXXX office about your loan today.  She puts her foot in the door so I couldn't close the door I had to push the door close and lock it to keep her from coming back in the office.  People in the back of the office came out to see what the noise was.  So running across the parking lot to my apartment and put the notice in my door.  Which is what she should have did in the XXXX place.  Then she speeds out the parking lot.   I called the XXXX security finance office asked for the manager was asked for my name.  I told the them a lady comes to the phone wouldn't tell me her name I tell her what just happened at my job.   She could have cared less that I was harassed and embarrassed at my job.  I told her that they are not to come back to my job or call and that they were banned from the private property.  I told them to contact me through the mail.  She starts defending the lady for coming to my job.  Beings to yell  going to sue you.  I hung up the phone.  I believe the lady that I spoke with on the phone was the sane lady that came to my job.  I called the XXXX office and let them know also what happened.  I spoke to the mgr I told her I would pay when I could u just started this job, which this incident made me look very bad.  So I may loose this job.  Because it was bad for this to happen XXXX
