gearbest Stealing money from people Internet

 I run a business at my home and have surveillance cameras already and decided we wanted more coverage. We looked around and decided on a set from gearbest. The first thing that happened is they advertise free shipping but they charged me over 50 dollars for shipping so that was my first e-mail to them . Which they never did respond to my question to why the advertise (No Shipping) but charged me. So then for 3 months I have been e-mailing them to where my camera's are?? They send back to site that always said same thing (processing). Now 3 months later I get a message that says that they cannot get me my camera's at all . They gave me 2 choices. Both which includes them keeping my money and me picking something else from their site. I have told them three times NO. I just want my money put back on my card and they keep sending me the exact same message again and again. I've now told them that I want to talk to a supervisor Asap. So that's where I'm at now. Don't know what else to do.
