Landline Whitinsville MA. Called me in February as well. A legitimate company does not call and not leave a message. NEVER ANSWER CALLS FROM NUMBERS YOU DON'T KNOW.
Received 2 calls in 6 days from this number but didn't answer, and no voice messages were left. Called back after the second time and pressed "2" in their audio menu to be added to the no-call list. However, they said Comcast customers may still be called (which I am) so I added the number as a contact on my phone and blocked them.
