Thank you so much for your post. I am wondering if you can direct me to the proper agency to report this sort of activity. I had the same experience and now have found that they are calling associated phone numbers today of family, etc and notifying them that I am involved in a so-called legal process and asking them for information. I'm sure there are many laws they are breaking and I hate to think of these people taking advantage of others who may not be as suspicious as I am.
Don't send anything to this company! I looked up the address you provided and it's a mail forwarding service. This means anything you send them could go anywhere and you don't have a way of tracking it!
