Calling threat to take me to court for checks that have never written trying to get personal information.

yes,I received a call from them stating I would be served at work. I told them I was referring them to my attorney.

this number, among a couple others, leaves messages stating I will be served at work and to call them. The first question they ask is, "what's your social security number." How can I get them to stop calling? Name they used this time was Alicia.

harassing messages left at several numbers. They state legal action will be taken and will not stop calling.
