Received a call today from this number.  Told that he needed to speak to my husband by name.  Said that his name was "Bob" and that he represented Herbal Groups and that it was for "problem with his order for a male sexual enhancement product".  Confirmed with my husband that he hadn't ordered anything.

Didn't answer the phone the second time, Caller ID logged a call that didn't leave a message from 201-383-4070. Found  that number on this site and a commenter in the thread for that number described a phone call exactly like the one that I had just had with this number, an hour before.

So I googled Herbal Groups and it's supposedly a company out of Van Nuys, CA. The contact number for them is 888-77-HERBS.
