Terrible Billing practices

I received an email stating that I owed for services past due. I responded to the email stating that I had understood my services to be canceled as I terminated my automatic payment method long ago. I was told that was not sufficient and that the account remained open. They sent me a bill for three months of a service that I had thought was canceled and I did not want. They NEVER sent a single message to let me know of the first or the second failed charge. On the 3rd failed charge, they finally let me know that my account was still open and being billed. They expect me to pay for all 3 months at $9.99 each. I was told by Customer service rep Mitch Chapman: "to get your account canceled you will need to pay at least 1 of the past due invoices and update this ticket after doing so and I can cancel your services." I paid for 1 month as I was told if I did so they would be able to cancel the account. They didn't cancel it after my payment. They stated that someone had used the server and they accused me of trying to get the service for free. I explained that I cannot control if outside users log into the server and I would have no knowledge of their activity as MANY people have the server information (as is the nature of voice chat servers). The company failed to notify me of any billing cycles until after the 3rd payment failed. They should have sent an email after each transaction to notify me whether the payment went through or failed. They should have also shut down the service immediately following the FIRST failed payment. They failed to take these basic reasonable actions and failed to communicate the status of my account to me until after 3 failed payments. The remaining balance that should be cleared is for 2 months at $9.99 ($19.98). They basically try to trick you into paying a small fee for services that you didn't even ask for.
