Beyond diet A scam to rip off some money off people Nationwide

I signed up for Beyond diet. I was excited to start. I decided to start the next day. I was trying to log me in the next day and it keeps coming wrong password, which I knew was right. I contacted them by email, but after 2 weeks they have not yet answered me. The next step was to let them send me a new password to my email, then it came up no email with this address can be found. The have taken my money so I did sign up. I think this is a scam if not why do they not answer my email and why can I not sign in? The next step is to get my money back from the credit company.
