Yea multiple calls from this number and the guy would ask a few weird questions and then hang up on me

I keep getting calls

Just got a call today and the woman used my first name (so they knew it was me) and was asked if I'm happy with my current magazine subscription. I asked what subscription would that be? She said the magazines you are getting. I asked again, which magazines? Then she hung up on me. I'm assuming this type of call is a "front" to confirm that this is my number. When I tried calling the number back (952) 455-4707, it said it is not valid. ???

Waited for the message to play, then all I could hear was breathing in the background.

Calls, heavy breathing. Nothing was said they just sat there
