Who called from 6015014963

I am tired of this number calling and when you answer no one says anything.

This person has called twice without leaving a message.

Someone from this number is calling asking if I want to purchase an extended warranty on a vehicle I don't even own anymore.

This number calls my home a couple of times a day.  Never leaves a message & I am not going to answer without knowing who it is.  Not willing to pay to find out.  I wish they would give up.

Thank you Aggravated - I am getting calls from this number also and haven't answered because I didn't recognize number.
I am also getting things in the mail wanting me to purchase an extended warranty on vehicles.  Sure wish I knew who is giving them my name and address - DMV, dealership, Insurance company?? They know the make & year.
