Incorrect provisioning of modem

I own an arris s33 modem, on the 2Gbps plan. I have not achieved a download speed higher than 700Mbps. If I check the event logs of the modem, I see provisioning for multi-gig support fails with the following error:
Config File Rejected due to Invalid or Unexpected TLV 11

I've been in contact with tech support 4 times now. I have been assured I would get a call back from "advanced technical support", I never received a call back.

Most recently, after being placed on hold to speak with a manager/supervisor, the call was terminated while I was on hold. I never got a chance to speak with the supervisor.

I am again, speaking with an "agent" through the chat interface, with no progress made to resolving the core issue. 

Any recommendations, that do not include renting equipment from Xfinity, to get the download speed I'm paying for?
