Who called from 3175595680

We get a call EVERY EVENING between 8:30 and 9:00 p.m. It will trigger my voice mail, but there is no message. The times I have picked up the call, there is no one on the line. The caller ID says NAD.

I get a call every day sometimes twice a day with no response when i say hello.

I get this call on my phone at least two times per day.  I have never called it back because I am afraid it will make matters worse.  I called the Public Utilities Commission and I am hoping to hear something soon, or for the calls to stop,.  Would love to know who this is or why they are calling me.

3175595680 is from NAD it is run by a group from india that want your information to cheat you out of your idenity and money.
