I was called at least 15-20 times in the span of three days. I work nights so I get woke up when my phone rings. Of course imc inc message ran. I got an operator gave them my number and name. Told them if I receive another call I will file a complaint with the FCC and file a police report for harassment. They took me off the list and put me on their "do Not Call" list.
IF You receive a call, forewarn them or pressing harassment charges, be pissy about it and aggressive, they are simple telemarketers that call you after filling out forms for some free crap or another on the internet.
