How do i stop paying you

Do not use "you" in your question since you don't talk to Unity Technologies here but to the Unity community. You haven't paid us a single cent. UnityAnswers is a platform where users help other users.

When you subscribed to one of the paid licenses you should have noticed that the $$anonymous$$imum subscription period is 12 month (1 year). You have made a contract with Unity and you can't get out of it before that period is over. If you stop the payment you owe Unity Technologies due to your contract you get in trouble.

If payments are not made, user's accounts are suspended after 21 days. After 42 days, any outstanding subscription payments are sent to an independent Collection Agency. Users are required to pay the full amount owing for the preceding months.
