Received replacement modem, /very/ displeased with receiving a discontinued refurbished device.

In a previous post, https://forums.businesshelp.comcast.com/conversations/equipment/time-to-get-a-replacement-for-the-old-smcd3gccr/633cf41548c60d55e60592dc , I asked about replacing my old SMCD3G as it was starting to randomly lock up, requiring a power cycle.

Getting a replacement was painless, credit to the reps for that.  But, what I got today...

The SMC is an old DOCSIS 3.0 than has been mounted on a wall, nicely out of the way.  What I received today is a Cisco DPC3941B, a no-longer produced/discontinued DOCSIS 3.0 huge monolith that has no provisioning to mount on a wall out of the way.

I was expecting for my monthly lease/fee, I would receive the current DOCSIS 3.1 'Comcast Business Router', like the CGA4131COM, not a 'Business Wireless Gateway' that is around 3+ years old, considered obsolete and discontinued by the manufacturer ( https://www.cisco.com/c/en/us/obsolete/video/cisco-dpc3941-wireless-residential-gateway-with-digital-voice.html ), and is not a 'drop in replacement' due to the physical design (and is missing the backup battery to boot, not that this matters as I do not have voice service, but it's the principal of the thing).

How would I go about getting something current?  This kind of feels like I was handed out leftovers and hoped that I wouldn't notice.
