Caller didn't leave a message on my machine and the caller id said "Minburn IA" which has no meaning to me so this is probably a  telemarketer/scammer. 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 Minburn, Iowa which matches the area code (515) and a service provider of Minburn Telephone Company. This is probably a scammer that is either spoofing numbers 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.
