No idea who they are as they left no message. I try not to answer any non-local calls that I cannot identify as all seem either some sort of scam or seeking money. I always tell those asking for charity NOT to call but send me something via e-mail or post. I NEVER GIVE MONEY WHEN CALLED even for things I support as I do not want to re-enforce the intrusions.
Those of you avoiding calls outside your local area should beware. This number IS local to me (where one of my best clients lives), spoofing to try to get me to pick up. I didn't, of course. Point being, just because it's local, doesn't mean it's a legitimate call. These mfers have made it so I hardly ever pick up my phone.
