called me twice on cell in a row  no message

We should burn this person.

Got a call from this # on my office phone asking to call back because "they are looking for our services".  Didn't leave a #.  I called back, machine answered and was put on hold forever....

First says "this is Mark Davenport", says they notice you do construction work in the area, and they scheduled more work than they can handle and want to hire your services, then at the end says
"again this is Mark McGinnon" and leaves 617-606-7052, and says to call us back or speak to one of the girls in the office...
I receive this call about once a week, but when I call back a voice prompt ask if you know you're party's or press 0. Then you're on hold...
Hope that helps.
Just the 2 different names in the same vm spells SCAM!

Asking about construction work - why do we have to deal with this
