Premium channel pairing on Comcast

I had to replace the hard drive in my Roamio Plus and of I course I lost all of my pairing information. After 3 hours and 3 different CSRs at Comcast, we were able to pair all of my non-premium channels, but no luck on HBO, Starz, Encore or any other premium channel. I tried the number I found on the forum and even the dedicated TiVo number on my Tivo.

Any suggestions on who to call next?

Thanks,
