Called on a Monday at 12:45pm (pdt) I answered after two rings, they disconnected.
Some web searches show this as belonging to (or used to belong to):
Novastar Home Mortgage Inc
700 Main Street
East Greenwich, RI 02818
(401) 558-0021
but anywho.com fails to find a listing for "novastar" (or "nova star") anywhere in R.I. and no data for reverse lookup so this number either belongs to someone else or is spoofed.
Yeah, ADT. . . I must have given my cell phone number to someone that sold it. Silly me. Now ADT is calling from several different numbers. I was able to contact a sales rep who SAID HE PUT ME ON A "DO NOT CALL" LIST. HE SAID. . . Right. Oh, well. . . Guess if I ever need security service, I'll KNOW NOT TO CALL ADT.
