718-841-6490 left a message on my work phone i can bearaly understand them but they leave american names  how can i stop them from calling

I received a call from William Page and his supervison Justin
Dept of Corporate Affairl Law office

The accent is very heavy

they have all my information how I dont know.... but they are telling me they have a legal case pending with my name and information...........but wont give me the copy of the affidavit

I had my Lawyer call them

That number keeps calling me to and threatening me.  Telling me im going to go to prison.   Now they are calling my boss at work.    I told them yesterday my lawyer was going to get them for harassing me.                    Is this even a legit company?

I received a call from someone who said their name is "Jason Brown," although it sounded like a female with a thick Indian accent.  She was threatening Darrell something, saying it was a warning, time sensitive, "don't disregard this message, call now; if I don't hear from you or your attorney, all I can do is wish you good luck as the situation unfolds on you."  I did not call them back.

Just received two calls from this group.  Jason Brown called first to inform me that I will be served papers through the court system and that they wanted my lawyer's information.  When I requested that I have the information sent to me so that I may verify what they say is correct, they told me that they could not since a number of attempts had been made via email.  If you can reach me by phone at work and on cell, why can't a "lender" that I used can't.  Asked that I do not receive any more calls at work and mutually hung up the phone.  then his "supervisor", Brenda, called back to ask what was my lawyer's name so that they could contact them.  Then she threaten to call my supervisor, even after I told them I was the supervisor.  Something has to be done and has to be done now!  Any help would be greatly appreciated.  This has gone far too long.
