I have been receiving harrassing phone calls from this number at Work and they have also asking for our payroll department. All they ask is for me to verify my SS # and I will not do it. I have no idea who the company is. They have called and tie up 5-lines on our company phone. This is jeopardizing my job.What they are doing is very illegal

Left message on answering machine, saying he found my name in a safe (?) and he had a question for me. He requested that I call him back.
