I received a message from this number from a woman calling herself Michelle Bass stating that she needed to get in contact with me but no information was given. She is calling from TX. I live in Los Angeles.

I also received a call from "Michelle" stating she has something to talk to me about but no other info was given. I live in Indiana

This person called me and my mom's cell phone and left a message for both of us on the home phone. Our number is unlisted and my Mom does not give her cell phone out. Who the hell is this woman?

She called my brother in Florida, on his cellphone, while I live in Arizona.
Told him it was personal and that I would not want it shared.
gave the name Michelle Bass.

She called me and said her name was Michelle Bass and I asked who she was with and she said ACT - Account Control Technology from San Angelo, Texas.  She knew my last name and was looking for my daughter's boyfriend . . . ??  I never give out my number either and have no idea how she got my name and number much less my daughter's boyfriend's name . . .
