Who called from 5086890300

Got a call on my cell phone from this number asking for someone else

no one there then they hung up

I saw 508 689-0300 listed as Conservation Services Group, 1565 N Main St., Fall River, MA.  The barely audible message they left me asked to call back on 1-800-632-8300. That's associated with MassSave, National Grid Conservation Services Group, 40 Washington Street, Westborough, MA. I think they do home energy audits.  Possibly just a wrong # in your case.

This is the number for MassSave.  An energy improvement organization in Mass.  If you sign up through their website for energy improvement rebates, they will call you to discuss details of the work being done.  The number is a good one.  Not malicious intent

just asked for mark and said I am call for a program not sure what than hung up.
