This guy has called me 3 times asking for someone else. After telling him the first time that he had the wrong number, by the third time I let my foul mouth loose on him. He kept saying that it was the first time he called like I dont have caller id or recognize his voice from the first time.

I've received two calls from this number in two days. I didn't pick up and no message was left.

I have received several calls from this number in the past week and whoever was calling would never leave a message.  On one occasion I answered the call but whoever was on the other end did not say a word.  I finally called the number back after several days of him/them calling me and not being left any messages.  A man answered and said "This is Johnathan".  I asked who he was or where I was calling and his response was "I said this is Jonathan, have you received a call from us?"  I asked him again who he was and who he worked for.  He said "You tell me, you called me".  I told him that I must have the wrong number, I hung up the phone, and blocked the number.  I was recently in the Los Angeles area and the timing is a bit ironic.  Could have been someone who came across my business card?

Have received a number of calls but there is no one on the other end.

This person keeps calling me. I dont answer. This is my new number. I have not given it to family or friends yet. It's the 7 th in 3 days.
