Who called from 2064960481

Called and didn't leave a message, called number. It was a recording trying to sell dental insurance.

I added their number to my call block feature.

If you have the time please answer it and waste their time.  Put them on hold while you get your (fake) credit card.  Come back and forget why they called you.  Fake having alzheimer's disease.  Make them lose money on each call.

I received a call from this phone number. When I answered there was no response on the other line for 7 seconds and then it just disconnected.

Just got a call from this number.  I answered, but got no response.  The call ended after about 10 seconds of silence.
