How can i apply my Free Credits of MARKETING or LOYALTY to my billings?

How can i apply my Free Credits of MARKETING or LOYALTY

From time to time i got Free Credits like MARKETING and LOYALTY, but i was never able to use them. When the month end billing comes there is no option to apply these or they are not getting auto applied.

Also these have some expiry dates, there is no flexibility to apply them before expiry date. Somehow i feel these are just of no use or i am missing something ? As i do not see any ways to apply them
