Increase in plan starting Jan, 2021

I received an email that my services are going to be increased starting in January 2021. I’ve tried calling to see what that increase will look like but have received no help. If you’re going to increase someone plan you should outline the specific details, not send out a list of everything that’s going to increase. I want to talk to someone to change my plan to limit how much my bill is going to increase. I’m very close to just cancelling Comcast all together (I have cell phone, internet, and tv) due to poor customer service and now an increase in price. Tell me what my new monthly bill is going to be and what my options are to change plans
