Query: Somewhat of a Problem here.

I have been trying to get in touch with someone from amazon.com.I ordered this book once with my debit card. An hour later, I received an email that my card had been declined. The email said that my order was canceled because of this, so I used another card and my transaction went through. This was 4 weeks ago. My book came in and everything was fine.A week ago, I received the second copy of the book that was supposedly canceled. I looked at my bank statement and I had been charged for the other book, too.Who can I speak to about this?
