they call at least 2x a day...

Have called at least four times today (to a company phone #)... most of the time no one is there.  Caller ID just says "Sharon"...  All I've been able to get is something that sounded like "Michael Manufacturing", but it's always been a bad connection so I'm not sure.

I got a call from this number twice over the last couple of days. No one is on the other end and connection seems to be bad. I called back and got an engage tone. I live in the Boston area.

A person representing "Test and Measurement World" magazine called to renew a subscription which I never had in the first place.  They were reasonably polite.
