I doubt that they will send "no" to anyone unless they mailed a check as payment.
When they cancelled my Aquila .22SV order after 2.5 years, I only learned about it from reading the CMP forum.
They didn't cancell your ammo order they just finally gave up on aquila to fill their order. So unless you actually cancelled your ammo order when they finally get some 22 in they will call you to see if you want what they got.
