Someone named James Davis called my father and tried to scare him by saying he had papers to serve on me but would not give any more info when asked. He said it was for "security reasons" I'm sure "James Davis" is an alias. I'm sure this "James Davis" has used many aliases in his pitiful life. I reported all the info to the FTC.
Received call from this number which had ID blocked. I did not answer. When I called back there was a message "This is "The Investigation Services" Please leave your Claim#" I hung up. This possible con artist uses this "authoratative" voice to try to scare you. My father also received call from someone this morning pretending to have papers to serve and left an 888 number with him. I have already reported this number: 888-382-4357 to the FTC today.
