who is this ringing my phone?

Calls every Monday with no voice message. I don't know anyone in MA.

Rings and hangs up.  Caller ID only says Massachusetts.  I don't know anyone there.

got phone call from this number - no voicemail

I (stupidly) answered the call.  The man with a heavy accent asked for me by my first name. I asked who was calling and he went right in to his sales pitch of claiming I have over such an amount of debt but make my payments on time.  I stopped him right there and told him he had the wrong number and hung up.  He called back today.  I answered and immediately told him to remove my number from their data base.  He got aggressive and said that they bought my number and I needed to tell him why he was calling first.  I asked again.  He said that I can wait for him to call again.  I reported the call to the FCC.  If he calls again, I will get as much info that I can so I can completely report him to the FCC.  If anyone else wants to answer the call and get the company name for me, go a head!
