Caller didn’t leave a message on my machine and the caller id said “XXXXXXXXXX CA” which is probably a scammer. So I ran 3 reverse traces using 3 types of traces and all were completely blocked. No person or business name, no general location(City, County, State, Country etc.) and no service providers showed up, however the area code is for Orange County, California. A legitimate business would never hide their identity and location by blocking a trace. This is the worse kind of scammer that is probably operating from a foreign country spoofing dead phone numbers while phishing for personal information and running some type of scam(s). This is an extremely high tech scammer so beware.  DO NOT ANSWER AND DO NOT CALL BACK FOR ANY REASON. Block and report to the proper authorities.
