TLG Great Fun Fraud 20$ rebate BEWARE!! Nashville Tennessee

I received a link to a great fun rebate from Supershuttle when I was making a reservation from Supershuttle. I called great fun. They told me that if I subscribe for a $1 no-obligation membership with them, I will be sent an email with two certificates for $20. I was told to print these certificates out along with my supershuttle confirmation with them to receive two checks for $20 each in the mail. I subscribed with them and they never sent me any email and mail them to Great Fun. The first time I called, someone told me that they had already sent me the email with the certificates. I was checking my email every day (including my spam folder) and I had never received anything from them. The second time I called, I was told by another person at great fun that the other person that I had previously called had gotten confused and that, I will be receiving my certificates within the next 48 hours. It has been 2.5 weeks now and I still haven't received anything from Great fun. I called Great Fun and told them that they were frauds and that they had cheated me. They did not dispute this fact at all. I have called my credit card company and asked them to block this company. Also, another way in which they cheated me was that they told me that they would bill my credit card $1 but charged me an additional dollar in the name of "Shoppers Advantage". The money amount seems small but they must be doing this to millions of people! BEWARE of this company. Please don't make the mistake that I made..
