I want to cancel my premium base their existence on how to do it?

Due to the wording of your question I'm not completely clear on what you want.  But I think you want to cancel your premium membership.......or maybe downgrade to basic.

To cancel your membership (either premium or basic) go to your dashboard, then expand "Account" and select "Cancel membership".  If you want to downgrade to basic go to your dashboard and expand "Account" and then select "Premium Membership".....near the bottom of the page you see where to change your account to basic.

If you are premium the changes will take place when membership expires at the end of the billing cycle.
