Bill got raised AGAIN

I need some help with my service. Everything is great, BUT the bill keeps being raised within months.. which is just crazy. I may be exaggerating, but I used to pay around $50, then around $70 after the promotion ended I think, and within a year or two, I’m now paying over $120. I love Xfinity, but I just can and won’t be paying this next month. I’m hoping to get some help, or I may just have to look for another service provider.
