Who called from 3147433010

This # has been calling for the past two weeks, several times a day. They never leave a message and when I try to call back it's busy. Anyone know what's up?

Called me tonight. Probably a bill collector.

It is a lady for Thomas Construction. They don't get the hint when you tell them not to call back.. I get 3 or 4 a week. Even if I needed something done, I would not call them now!

they call from like 10 different numbers and deffinatly dont get the hint when you tell them not to call
