Every day I get 1 to 2 calls from this person. If I block them they call on another number. If you answer the call, no one talks then they hang up. If you block them they call via another similar number. They know immediately that you blocked one number and use a different number the next day. If you call them, you get a hold and will be answered. No one ever answers. Total harassment. Who, why? Can someone stop them. I can't answer any unknown phone numbers. How can I receive my hospital appointments etc with this going on.
