Remove me from your call list. Thank You

A guy saying that his name is David Parker called saying that there is some kind of fraud on my account. He also call my friend (how he got her number I have no clue). He became very angry and threatened her with 'charges.' He also told her not to 'be cute' when she began questioning him. He would not give her any information other than to say that is is emergent that I call back. My friend's brother (a REAL OFFICER of the law) said that he can not do anything to her and that is a scam. He told me to report him right away!!!

Number calling my phone portraying an office of the law. Looking for information on a friend who used me as a reference.

Ms. Taylor said she was on the way to my job to serve me a summons.

got a call from this number. Some said said hello and hung up. when i called back the phone is disconnected. I guess this is a spam.

Receive many calls from this number, they never leave a message. I have it blocked on my phone but would like to know who it is.
