I personally haven't answered any of the Maynard, MA numbers that have called me. Yeah that's right. There's more than one number. I blocked their first one a month ago. If you're getting called by this one, you've probably already have (or will) see this number: +1 (978) 243-2217
From what I gather on other sites, it's a car warranty scam or something along those lines. If you do answer for some reason, and I'm sure you can easily make them hang up by questioning them.
