Caller ID: WIRELESS CALLER Machine answered and female, thinking there was a live person on the line, said hello and then hung up. Call center background noise.
Caller didn't leave a message on my machine and the caller id said "Wireless Caller" which usually means telemarketer/scammer since every legitimate caller I know leaves a message. So I ran 3 reverse traces using 3 different types of traces and all were blocked for a person or business name and the only information was a general location of Long Beach, California with 3 service providers of Allegiance Telecom, Inc.-CA, New Cingular Wireless PCS LLC and XO Communications which is a favorite for scammers. This is definitely a scammer that is either spoofing and/or using a voip system to phish for personal information while running some scam. A legitimate business would never hide their identity and location from the public by blocking 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.
SCAM! They called on a Sunday (a red flag) offering home repair estimates. Within a minute they were threatening to shoot me and insisting that they would send someone to my home to shoot me. The telemarketer bragged about being able to carry out violent crimes against people they don't like.
