They just called me.

called and left no message, number listed as not in service when I called back from a landline

These phone calls have been coming into my home for some time.  It is not a valid number and I am sure to is a fraud.  Catch these people and do whatever you have to with them, I am sick of it.

Got calls from this number twice today, it's from an auto Insurance company said I left contact information on their website but I never do that

I finally picked up the call after receiving three calls on my cell phone today.  The caller identified themselves as a representative for National Savings Center.  He stated (in broken English) that insurance company rates had gone down 40%.  He asked if I still own my vehicle and identified the vehicle I owned.
