Can I turn off automatic rent payments on my account?

The "Electronic Payment Addendum" in the tenant lease agreement (page 2) authorizes Alcove to charge tenant's account on behalf of the landlord for their monthly rent payment

No. Alcove’s payment system is designed to automatically charge rent on the due date of your payment method on file for active lease agreements. Since automatic payments are part of the signed lease agreement, we are unable to stop auto payments or remove the payment method while your lease is active.
