My son-in-law has been getting calls for me on his phone and I've never given out his number to anyone. Who the heck are these guys.

They identified as advanced location services. The guy barely spoke English. They were asking to verify that such person has such number.

Can no understand a word they say in the message left. They some how c

They contacted an Aunt who is no longer married to my uncle for 20 years now and is not at all related asking about me. How they got her information is a mystery. I dont even have it and was contacted about their call threw 3 others down the chain. Seems like a phish. But i cant understand the words coming out of their mouths.

Not sure who this is or how they got my information; but, like the other comments here, I couldn't understand anything she said other than a name.  I asked her to repeat herself but could not understand anything.  Not sure exactly what this is.
