The terms and conditions state clearly, that after the initial month, you will get charged and you will have a one year subscription. The early termination fee is stated in the terms and conditions. I recommend that next time, you take a subscription, you read all the relevant information. It's for sure not a scam.
To get you out of this situation, I recommend you to contact Adobe customer care and to negotiate your way out. Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. Pop-up blockers need to be disabled! If the chat window fails to open, or is non-responsive, use a different device to start the interaction.
