Low Pay Card / Scam and cheating

I did not realize they were going to go into my checking account numerous times and when I tried to cancel over phone was told I had to wait to receive welcome kit before I could cancel. Well, I have not received the kit yet and it has been 3 weeks since that conversation with a csr. After visiting their website, I discovered that I could cancel over the phone but was told that I could not do so. This card is a scam and I hope by writing this letter I can prevent someone else from falling for this scam.
