It's a company called Herbal Group, and it's a scam.........I didn't answer the call, because I didn't recognize the phone number on my cell phone............I called the number back, and a girl answered and said "Hello, my name is .......welcome to Herbal Group", then I hung up..........and Googled Herbal Group................here is what I found:

DON'T ANSWER ANY CALLS FROM THEM!!!!!!!!!!

Any ideas who this might be?

This number calls me all the time. Says from Albemarle, NC leaves no message on answering machine. I never answer calls from people I don' t know! I love my caller I.D.!
