I received a phone call from this number at work and he refused to tell me who he was, only that he was calling from a Law Office.  I asked him what he was calling about and he told me "You know what I am calling you about, and I won't give you any more than that."  He had a very thick Indian accent and was difficult to understand.  I informed him that he either needed to tell me what he was calling about or stop calling me.  He informed me that I could either pay him the money or he would continue to call and harass me.  I told him to stop calling and hung up.  8 PHONE CALLS LATER of me telling him to stop calling and hanging up on him, informing him that I was going to report him for harassment.  He yelled at me and stated "I will just call your employer and you will be fired immediately, you will lose your benefits, you will lose your pension, I will have your house taken away from you.  You are a deadbeat and I am wasting my time."  I told him to go ahead and do what he felt necessary, but if he contacted me again, I would file charges against him and his company.  The phone calls came from different numbers every time.
