SCRA National guard question

I’m in the Air National Guard and have been on some form of orders for over a year now with only one small gap in orders. I am just finding out about SCRA benefits and would like to take advantage. I’ve already seen on the SCRA website that my state includes title 32 orders as active service eligible for SCRA.

Is your credit card/ bank etc. required to refund the interest paid while on orders? (in my case a year+ worth of interest)

How long after orders end do these benefits last?

If I’m on different sets of orders (ex: 57 days, 17 days, 60 days, etc etc.) and but they are consecutive, will I need to re verify my orders each time a new set of orders begins/ ends?

Lastly, in the pinned post on this page I’m seeing that sometimes the card company customer service reps can be cryptic about these matters and not very helpful. Any advice on how to guarantee I get the most out of this when navigating getting set up?

Thanks for the help in advance. I feel clueless with this and from what I’ve gathered researching this, it could be life changing and very helpful.
