Caller didn't leave a message on my machine and the caller id said "XXXXXXXXXX CA" which probably means telemarketer/scammer. So I ran 3 reverse traces using 3 different types of traces and all came up with Robert Conlin of La Habra, California using a service provider of Verizon California, Inc-CA(GTE) which is a popular choice for scammers. This is definitely a scammer that is spoofing this number. A legitimate person or business would never hide their identity and location from the public by blocking caller id with X's and then be so easily found by a trace. DON'T ANSWER AND DO NOT CALL BACK FOR ANY REASON. Block and report to the proper authorities. Phone companies should be held responsible for these types of calls since they are making money from them by providing the systems and services that these scammers use and possibly farming out numbers too.
