My promo is about to expire and looks like it will be going way up.

D-man, 

I'll be glad to help cover some new options. While online, you can also take advantage of the awesome Xfinity App to manage and make any changes to your plan. The primary user or manager can log in to make adjustments at any time, and the plan builder helps find the right plan super easy. There, you'll find the same offers we have on our end as well, which is great. For more direct help, please send me a direct message with your full name and service address to get started.
