Marin cca first National Card ripoff Las Vegas Nevada

I just received a call from a person at Marin cca first national card first national credit. They offered me a $8500 credit limit with only a $99 down payment. I was advise by a friend to look at this website and to my horror have read multiple articles about how they have ripped people off. They still have not access my bank for the money (march 16th), how do I stop them from going into my account? I just want to stop the whole process now and they stated that I would just have to write to them prior to the 16th and they would not take my money out of the account!

Should I call my bank and inform them not to honor that transaction? Or should I just write to them now to stop the order? I still have not received the package and I still haven't purchased anything from the account and will not use the card. I was just trying to raise my credit score! Any advice would be greatly appreciated.
