Pricing adjustments for long-time Xfinity customer

I have been on the phone for 2 hours today trying to speak with a manager regarding adjusting the pricing for my Xfinity services. I have been trying since January 2024 to adjust the pricing without going through the inconvenience of changing my current services or cancelling completely to re-enroll under someone else's name. I have been on hold for 30 minutes now for a manager, and that is after listening to a condescending agent tell me that a manager is only going to tell me the same thing they did. As a last resort, I am reaching out on this forum. I re-built my current Xfinity package online and as a new customer, would be paying over $160 less each month for the same services. How is it acceptable to treat loyal customers in that way? At my current monthly pricing of $290 for Xfinity services, losing me as a customer would cost the company over $3000 a year. I am just about ready to cancel Xfinity and sign up with a competitor like AT&T, which is offering me a much better monthly deal, in addition to an extra $200 just for switching to them.
