I keep getting calls from 215-535-5040 from a (sounds like )Jeff using broken English saying he he with the National Crime Investigation Bureau and if I do not respond I could be arrested and/or my assets can be taken. He calls my cell phone 5 times a day and calls me at work and leaves me messages on my work phone 2-3 times a day. I am reporting to the FTC however I do not know how to get these people to stop calling me. Any other suggestions?
