Who called from 3147320479

This number has been calling me 1-3 times a week for the last three months. Hangs up if I answer.

I called the number back, using *67 and it said this is an attempt to collect a debt.
Considering all the medical bills I have who knows...

Called me on 11-28-16....I didn't answer and they left no message.

I received a  call from this number and couldn't get to it but they didn't leave a message so I called it back and the company name was FSBC or something like that with an attempt to collect a debt, I hung up... figured if it's real they we would leave a message.

They called, and tried to get me to verify personal information. I asked several times what it was pertaining to, told me they wouldn't say until I verified. I wouldn't, and they told me they would send a letter in the mail, then wished me luck. They tried to intimidate me but I wouldn't take the bait. Scamming bottom feeders!
