It is possible you can credit me for the download once I get the code?

I just upgraded my phone to use for t-mobile service. I currently have nokia 5300. I have received a brochure that with the code I can download for free 3 songs. I didn't go to websitehttp://music.yahoo.com/certificateredemption to get my code. I did this incorrectly and was charged for all three download. It is possible you can credit me for the download once I get the code? Your istance will be appreciated.
