Caution, 336-608-4636 is a "spoofed" number, which means that whoever called you "tricked" your caller ID to display an incorrect phone number. Telemarketers do this so you cannot complain, but they failed... you can still file a complaint here to fight back against unethical telemarketers.
I picked up the phone and there was silence, which was only broken by a beep, beep, beep, which indicated to me this person was recording my voice when I said, "Hello". That's an attempt at intimidation when a person hears no voice, no identification, or anyone giving a reason for the call, just a beep where someone is recording your voice. It doesn't work. i hate to tell you. I'm not easily scared.The only identifier that came up was the letters, "CPC".
