Xfinity Mobile account and Xfinity Internet accounts not linked

Hello!

I've had Xfinity comcast for my internet across multiple homes and many years now and, historically, it usually takes a couple phone calls of digging to get my previous accounts/addresses removed so I don't appear to still have multiples. 

But today I write to you in the hopes of attaining what has always been promised and hoped for. Connected Xfinity mobile and internet accounts. Especially now that there's promotional pricing and bundling. (I had Xfinity mobile when it launched years ago now, hoping for bundling someday)

My new home that I'm moving to, the neighborhood has promotional rates with Xfinity. I created the new address, linked the accounts and was prompted to link my Xfinity mobile account to benefit from the 1 line for a full year of Xfinity Mobile. Upon login I was met with "this account does not currently have any mobile lines associated" Logging directly into the portal in a separate window, both with email and phone #, yielded the same result. The phone number I'm inputting is of course my Xfinity mobile number as well, so I know it's correct.

Is it possible to have these accounts linked correctly so I can maximize on the bundle and discounted rate?
I made sure to let my previous promotion lapse and the old address will be turned off in favor of the new, so I don't have conflicting promotions either.
Presumably, if it's all bundled, it'd be one payment coming out for one whole thing (internet and mobile) which would be an appreciated change as well.

Thanks!
