I may be late on this, just wanted to add some info. <o:p></o:p>
I created a new sub to move the resources to, but it says I can't move them from a disabled sub.<o:p></o:p>
Resource movement is only possible if source and target subscriptions are active. Since, you do not have access to the disabled subscription, the action to perform resource
movement isn't possible. So, you need to contact Azure subscription management team by creating a support ticket as said by "Vaibhav" and request for subscription re-activation. <o:p></o:p>
How do I pay any outstanding charges and reactivate? <o:p></o:p>
As said in the previous comment, you cannot perform any action on a disabled subscription. For changing payment method, you should do it before subscription expiration
date, post that only the support team can help you further.<o:p></o:p>
