This is a scam # the caller says a law firm needs to send you legal documents, doesn't say what they are for, then says if you don't respond to the call the caller will be at your place of employment the next day. This would have been a bit tricky since I was unemployed. Another scam is you are being sued by a law firm for an bounced check. No one is sued for that, if there were a problem your bank might call, but not a scam artist. Also a lawyer would file papers with a court and the court would send papers in the mail. These people will change phone numbers hoping you will answer the phone- ignore them. They need to get a real job.
