These [***] did the same to my account. its was charged for 9.94. I made no such charge either. I called and filed a fraudulent complaint against them to the FTC. Be sure to cancel your check card. I know I did as soon as I saw the charge.
I also got a charge for $9.89 on October 5. I called the number and spoke with "a representative" and was told the charge would be removed. That was a month ago.
