Problems with payments

I know that I probably saw Grade Saver on the Internet. I was curious I looked into it but never used it for anything yet. I am charged 1999 a month for 12 months. I just canceled it as of 628 and it expires on 720. Please do not charge me for any other months. This was a total mistake. I did not know that I would be charged each month. My phone number is 225-939-0968. My name is Wanda Harrison email is [email protected] . Email is all lowercase.
