I suspect a debt collection or something along those lines.  They represent themselves as a law firm which they are not.  I had a local law firm do some preliminary because the law firm name they give is very very close to a real law firm that I recognized so I had them see if this firm was impersonating them.  They were not but the name was totally ment to confuse people.  When I contacted them, and talked with someone they were very abrasive and very pushy and condecending almost to the point of threatning and they raised it that way, I did not provoke.  Whatever the firm and the number is local to Milwaukee is bad news no matter what their business is.  When I asked the guy what type of business they were in, he wanted nothing to do with telling me other than he wanted my phone number so he could cancel the phone calls that were in error.  They were in error cause they were going to my daughters cell phone.  Not likely he was getting my number.  I had verizon block them.
