harrassing and threatening phone calls

They have been calling me for a couple of weeks. They claim Andre (whoever he is) used my number and they gave him a loan. I said I have had my numer for a couple of years and she called me a f*** liar. They call daily telling Andre they want to give him another loan, but when I called to tell them to stop calling me, they said he owed them a lot money. I asked why they would call with loan offers if her was deliquent? SHe called me  [***] and I played the recording for her. Then she called me a [***] and sad she was going to cut off my tits and shove them down my throat!
I asked to talk to her boss and she said there is no one here who cares about you, (more insults added)! We can call you as much as we want as long as we claim we are calling Andre. My borhter grabbed the phone as she hung up and called back. He got another man who told him my phone number wasnt in the system and WE were harrassing them! He also asked to talk to a supervisor and the man threatened him also. We never heard of Andre or Cashcall before these calls started coming in.

They are crazy!
THey are violent and threaten poeples lives!
