Discovery Bank too good to be true?

Yesterday I wanted to apply for Discovery Bank. I completed everything and then I came to Hellopeter to read the reviews for Discovery Bank - and almost all were negative!! I immediately requested my application to be cancelled, but no one rep****. This morning I received an email that my card is on its way. Minutes after this I received a phonecall, but I did not answer. It was the delivery guys with the card! After all the negative reviews I really dont hope that I am going to be charged for this - seeing I dont want it anymore. I can say this - the service was very fast, but unfortunately your reputation is not good...
