have called many times, sometimes three times a day. when answer will not leave any information because
ask for husband and he's not home. we have blocked the number now.
Caller ID said IMC. They hung up before my voice mail greeting was done. I wouldn't have answered it anyway.
Multiple companies have that name. Out of the ten or so references to IMC on Google, I pick International Mulch Company. One day, if I am in a really foul mood, and if they call again, I will answer, and place an order for mulch.
More disturbing than a standard hiding-the-source scam, the one comment that I saw reported receiving a message thanking him for his interest in the "NRA". Could be another version of National Recovery Association. And significantly, they started calling, two days after the National Recovery Association stopped calling, which in turn was three days after I reported NRA to the FTC.
This one is going to take some work.
Neutral Tandem-Missouri, LLC appears on one entry in one thread,

and their Washington entity seems to be used by others as a source for funneling scam calls.
