Ticket Galaxy Rip Me Off  just a phone number and email Internet

 I purchase tickets to a concert in San Jose, CA. I notice I was over charge on the service fee of 48.62 and when I got my credit card statement, the charge was over 750.00 for 4 tickets. Did some research on the email I recieve and notice they charge a service fee on each tickets. I called and question the fee, the lady told me that the service fee is on each tickets and I told her that I agree to 48.62 service fee, but I didn't agree to a service fee times 4. She told me there was nothing they could do. I told her I will contact my credit card, and she told me to go ahead, but they can't do anything. We will see.
