Strange/multiple refusals from Cox when adding my own Arris TG1682 to an existing account
I called Cox technical support to swap out my current Cox-owned cable modem with my own that I purchased online. I told them it was an Arris TG1682. Okay, that's just fine, it is on the supported list, they tell me. I gave them the serial number and that's when I got all sorts of strange and conflicting answers (just from that one representative) of why Cox can't switch my rental Cable modem over to the one I purchased:
Representative's Reason 1: "It isn't in Cox's inventory, so I can't provision this." Because the cable modem isn't actually owned by Cox, I cannot add it into my account, I'm told. Does this make sense? Actually, someone else (outside of Cox) tells me that if the serial number was in their inventory, then they couldn't provision it because it belongs to Cox and was rented out to another customer and needs to be returned!
Representative Reason 2: "Customers aren't allowed to bring their own modems to Cox." I mean, this seems silly, right? In the past, I've had Cox representatives tell me that I can go to Best Buy and get a cable modem. Before I bought this one, I looked it up on Cox's own list of Certified Cable Modems. The list said that Cox wouldn't be on the hook for supporting/replacing the device itself, but that it would work with their network. But now that I have it, I'm not allowed to use it?
Representative's Reason 3: "You don't have telephone service, so we can't provision this" (for Internet-only service). I currently have a Cisco DPQ3212 that I'm currently renting from Cox. A month ago, I ported my telephone number to a wireless carrier. (I might port it back, which is why I want to stick with a VoIP capable modem.) Right now, I'm paying Cox $9/month (or so) in rental fees, so I'm trying to avoid that. But I'm told that because I don't currently have VoIP service that Cox can't provision this particular replacement modem on my account because it has VoIP features? Is this the real reason? Because if it is the only thing holding me back, I'll add a minimum-tier VoIP service onto my account just to get it done.
1. What is the real story?
2. What do I say to the next representative that I talk to in order to make the provision the cable modem that I purchased, is not owned by Cox, and is on the list of certified devices which work on Cox's network?
I appreciate your time. Speculative responses are welcome, but I really would like an authoritative answer! :)
