Just spent 2hr 45min on Xfinity Support Call with No Resolution!!!

I just experienced the worst-ever experience on an Xfinity support call (2hr 45min+ with no resolution), and after being a customer for 20+ years that says a lot. I'm looking for recommendations on how to contact Xfinity Leadership because this was such a horrible situation. In years past there was a way to contact the corporate office online, and someone would follow up. It appears that the channel has been taken down. Any suggestions?

This is all due to the so-called Customer Loyalty Department which I contacted because I was looking for options to reduce my bill ($300/month!). I'm currently on a grandfathered bundled plan of internet, cable, and home monitoring. After spending 1h 20mins with an agent in Customer Loyalty they couldn't figure out how to properly update my home security plan, and he transferred me to a tech support agent. The tech support agent couldn't modify my plan so after about 40 minutes with him, he transferred me back to Custom Loyalty. The second Customer Loyalty agent seemed a bit more competent but ultimately she couldn't figure it out, and without my agreeing she transferred me back to another technical support team. The technical support person said he couldn't resolve the issue so he transferred me back to Customer Loyalty.

At this point, I was livid and asked to speak to a Supervisor and of course, one wasn't available. So, I'm stuck waiting to see if one calls me back. I made this call to give Xfinity a chance to keep my business rather than me cutting the cable. What a massive fail!
