Unauthorized charge

I noticed on my bank statement a deduction of $75.00 (www.fb.me/cc) which I did not authorize. I don't know what it is for or why it was done. I never purchase or use any services which require me to pay for anything on this site. I want this charge of $75.00 removed and not to do this again unless I have been contacted first so as to confirm my purchase.

Thanks in advance for taking care of this problem. Please notify me when it is taken care of too.
