Promo ending, bill continues to sky rocket

My promo is ending.  I have the old Triple Play, tv, internet and voice.  My bill is about to go up to $220 next month.  I like Comcast and the live tv and On-Demand but at these prices, I am being forced to look into cheaper alternatives like the streaming apps that most of my friends and family have already switched to.  I have chatted with a couple agents a few months ago and they told me I am getting the best price for my plan.  I don't want or need cell phone service from Comcast.  I just want to be able to keep my current services but get a promo discount.  Please advise if there are any promos for my account.  Thank you.
