I have been receiving phone calls on my private cell phone from XXXXphone number. 
I live in XXXX and it is a XXXX area code I do n't recognize. 
They have never left a message, so, a XXXX ago I called back and askedthem to identify themselves, name of company, and what this is about. 
They keep trying to seek verification from me. I will not unless they tell mewho they are and what this is about?. I am recently widowed and was hospitalized in XX/XX/XXXX-XX/XX/XXXX a number of time and deemed XXXX on XXXX. 
This evening he called with this number XXXX and left a message threatening me with a lawyer. 
I read your information and it states his suppose to mail me documentation after the initial contact. Which was a XXXX ago and I have not received. I do n't even know the name of the company or who the caller is.
