how can i cancel my profile without paying?

When you 'click to agree' to the subscription terms while buying a subscription, that means that you really do need to read BEFORE you enter your credit card number to buy a subscription... See this page for more information, including a yellow highlited section from the subscription page https://community.adobe.com/t5/account-payment-plan/cancellation/m-p/12153645

To Cancel https://helpx.adobe.com/manage-account/using/cancel-creative-cloud-subscription.html
-READ THIS https://helpx.adobe.com/manage-account/using/creative-cloud-subscription-terms.html#cancel
-do be aware that cancelling early means paying 1/2 of the remaining subscription time as a fee
--this is cancelling AFTER the trial converts to paid and BEFORE the end of the subscription
-or have Adobe support cancel your subscription using the "autoOpen" Chat link below

This link will go directly to the chat option
Type "Agent" in the chat box to bypass the chatbot and be connected to a person
-Meaning type in the word Agent without the quote " " marks
