Whomever has historically called for several months, twice, three times a week. Seriously, I would call back if you left a message and had any factual business with me...After this many calls? No message? This firm must be paid by the dialed number and not on any return interest...that's a real waste of my time...and whoever's payin' em!
I made the mistake of answering becaus I recognized the last 4 digits of the phone number, without an area code. It is from some survery outfit and I hung up on them. I believe the caller was using a fake phone number as they don't come though without the area code. Perhaps that was done deliberately. The caller ID name was SSI.
