How in the dickens do I get the latest DVR?

OK, here goes. I have Internet 1000. Great speeds too, 940-960 Up and Down. I have the Pace IPH 8005 DVR. Not a slouch but there is better out there, especially for fiber. I have twice requested a IPH 8110 and both times I ended up with equipment from a decade ago, a Arris/Motorola VIP 2550 and the last one was a Cisco IPN 4320. Sooo, it is going back too. Would much rather keep the IPH8005 over that junk. Do equipment replacement personnel have absolutely no control over what the warehouse ships out? I would rather get a "We have no 8110 in stock at the moment" rather being shipped 10 year old low cap and low performance DVR's. This should be a real easy fix....
