So frustrated with xfinity

My current deal is coming to an end & I'm currently paying 150$/ month for 400 mbps & unlimited data & popular TV so now I have to pay 166$/month for 300 mbps & unlimited data & popular TV is now called TV plus but it's the TV that has 125 channels but here is the kick in the gut if I was a new customer I would only pay 140$ per month for 5 years! The internet is 45$ per month & the TV plus is 95$ per month. I'm so sick of xfinity & there terrible business model that prioritizes new customer over existing customers & I've been with xfinity since 2013 & I never pay my bill late & even went to their cell phone service to get a discount on my other xfinity services & they are in danger of losing me as a customer all together!
