I got a phone call from a private number. When I answered the phone, the lady asked for me by name. Then she asked for my address. I refused to give her my address and asked what is this about. She stated, she could not tell me. I would have to call this 855 number and they would discuss the matter with me. I was also given a 5 digit case number,to give to whoever answered at the 855 number. I then asked the lady, where is she calling from? She refused to tell me. I asked her is this a law firm? She refused to tell me. She then told me, she is working out of her car for someone. And she has a sealed envelope with my name on it that needs to be delivered to me. I should call the 855 number so that she won't have to show up at my house. Her last statement to me on the phone was, she would call me back in a thirty minutes to see if I called the 855 number. After trying to find out where 855 area code is located, I have learned that this is a scam. Ever since this incident on the phone,this lady has been calling me from this private number, leaving threatening messages, everyday-several times a day.
