Taking payments from my account for three years for no reason

I just learned today that Digital River has been taking $68.14 from my account since 2013, it is now January 2016! I have never heard of this company nor have I knowingly gone into any agreements with this company or any of its subsidiaries. I demand a full refund immediately. These charges are being disputed. I am contacting my lawyer for further action if I do not hear have back from a manager of Digital River or DigitalRiver.com Thank you.
