Purchases refunded on compromised account?

So, essentially, my son did something that compromised our family Microsoft account. I've submitted everything to Microsoft to try and recover it, but it's been a week and I'm no longer real optimistic.

My biggest concern at this point is the money I've put into digital games. Since I can't even access them with a new Xbox account, what avenues do I have for refunds if Microsoft says they are unable/unwilling to restore my original account?
