Complaint Review: fulfillment Center

I am receiving merchandise that I have not ordered and am being charged for these on my credit card.  The company name on the package is Fullfillment Center.  I am not sure if this is the real company name or some sort of warehouse that ships merchandise for various companies.  I tried to call this company and had trouble getting a person to talk to.  When I finally reached a person I was not told anything and that they would have to call me back.

I received an email this afternoon and it looks like another packge has been shipped to me.  I have a dispute filed with my credit card company about these charges on my credit card.  I cancelled my credit card and they are going to issue me a new one. 

This all started when I saw an ad advertising some sort of vitamins to give you more energy.  I decided to give this a try and allowed them to send me a sample for approx $5.00.  Now they are sending monthly supplies and billing my credit card.
