413-241-6695

This number calls my house phone repeatedly with no message.  Caller ID says IMC.  When I called it back it is the NRA

This number calls daily.  Googled IMC and came up with marketing company, investment firm,  and debt collector.  I have nothing to market, no investments and no debt!!  I checked my credit reports to ensure that I hadn't been the victim of identity theft.  These phone calls are getting ridiculous.

I have gotten 2-3 calls daily from this number. I called it back and found out it is the NRA (National rifle association) If you hit #1 saying you want more info on the co. a prompt comes up and asks "Please enter the 10 digit phone number you would like removed" It then says that they have 30 days to remove it permanently. Let's hope it works!!!

You appear to be right.  I did as you suggested and it was the NRA and #1 seems to do the trick. Thank you.
