Where to complain about inability to disable DHCP on Telus Wifi Hub?

[wireless]

I really need to use DNSmasq for local DNS resolution -- I work from home, and need to delegate DNS differently depending on the target domain. Per this post, the LAN DNS is not working in my wifi hub, so I need to use my own DHCP server. It sounds like this isn't possible.

Where in Telus should I direct a complaint about the Wifi Hub firmware, in order to give it the best chance of being escalated to the manufacturer?
