They are Scammers

I was told I would receive a $100.00 card to spend on anything I wanted but I got the letter from them and they told me I had to join their membership in order to get the card.  I was told that I would receive the card and try it for 30 days before I had to pay any money.  I got the letter today and they said that I had to join and use the card in order to get the $100.00.  This is a rip off and a big SCAM.  The letter says that I could get help but when I tried to call I was told they were closed and the letter said I could get help 24/7 that was another lie.  I don't like when I am lied to.  I would like help in this problem and I want help as soon ASCP I am going to report this company for fraud and stealing.
