In my credit card bill this month (April 2011), I shocked that I was billed 2 transactions those I never did. First one billed by "DRI*APP WORLD ORDERFIND.COMMN" $1.99. The second one billed by "RAPIDSHARE.COM CHAM CH" $ 19.90. I attached the billed part.

I never ever use this credit card for online transactions. So, how to get a resolution for this case?
