I've been getting these calls for two days now.  thankfully my caller id located the number and I have not benn answering from these jerks

continues to call, despite not answering cuz of the unknown, I'm going to report it to the DO NOt Call site, it works

A very mechanical voice, although it was a live human, indicated that he was from a research firm that was conducting a survey. He then said, "I want to assure you we are not trying to sell anything, this is truly a survey." or something to that affect.
The first question he asked (without receiving any approval to go ahead from me) was "Are you or anyone in your household employed by a bank or a financial services company?" I said "I don't really feel comfortable ..." at which time he interrupted; his voice changed dramatically to a more normal cadence and tone and said "OK thank you for your time." and abrubtly hung up.

Received a call from this number, they did not leave a message. Tried to call it back but all it asked me to do is to enter a number for a mailbox that I would like to check.

no message.
