Caller didn't leave a message on my machine and the caller id said "DIR ASST CA". Directory assistance in California is "411" and why would they call anyone. And "555" is a movie number. So I ran 3 reverse traces using 3 types of tracers and all were blocked for an identity [person or business] and only 1 came back with a general location of Fresno, California using Multiple OCN [Operating Company Number] listings as a service provider. Related Tel# 714-555-6617, 714-555-0155 etc. all starts with "714-555" and the handle "DIR ASST CA". This is definitely a scammer that is either spoofing or using a voip system to phish for personal information while running some type of scam. DO NOT ANSWER AND DO NOT CALL BACK FOR ANY REASON. Blocked and report to the proper authorities.
