Who called from 2153099032

I get calls daily at different points of the day on my cell phone. No one has that number except work asscoiates and a few friends.  I won't answer because I see that it originates from Levittown PA, notorious for scam calls like credit card offers, lowering electric bills, etc.  Is anyone else bothered by these people?

i have been getting calls from them and everytime i ans it and say hi they do not ans i am thinking about having them blocked

Michael called, but this VOIP call got disconnected before I could get his pitch.

Getting multiple calls a day. No message.
