I just called them back - it's a company called HGW hocking water treatment systems, the person I talked to said he would take my name off the list when I told him AI already have systems in place.
I bought a house and received a "last notice" in the mail. I thought it was documents, But NO. It was so these people could tell me congratulations and now keep calling and calling to promote their product. When I told them they are calling a business, they said they would quit calling. Lasted about a week. Now the calls continue. If I ran my business this way, I wouldn't have a business.
