Cannot Download Pages for Free

I have a couple 16GB iPad Air 2s that have been purchased in the past couple weeks that I've recently activated and created Apple IDs for but when I went to download Pages the App Store is requesting payment information now.

I've removed and added back the account, rebooted the iPad, and even wiped and re-setup the iPads but still can't download Pages for free.

I setup the all the iPads to have different IDs that reflect there asset tags we place on the devices and this has happened to 3 iPads so far.

We also don't have a MDM yet (I really wish we did) so they're basically setup manually as single device.

Any ideas on what I can do to get this fixed while I wait for Apple to answer my support request?
