Customer Loyalty/Retention Dept.

How do I get in contact with the retention dept or make arrangments to cancel my account? Today after hours in chat with agents trying to get the best deal possible on my existing account. For whatever reason their chat was glitching and kept disconnecting and reconnecting to a new agent. I ended up with at least 7 agents trying to accomplish the same thing. Finally after getting someone to stay in the chat the agent told me Also, let me inform you that Xfinity has launched some promotional deals on new accounts. Since you are an existing customer, you will surely get a better deal than that. That person was then disconnected and then reconnected to yet another person who confirmed to me that: Yes, I have shared an even better deal with you. But then after reviewing the deal I found that it would actually cost over $700 more per year than other existing deals for which they refused to honor. Even after being transferred to a manager the manager refused. They even admitted that it said exactly what it said. And then did nothing more than copy and paste form responses without even bothering to remove the quote marks. 

The best part of all this. In the middle of going back and forth towards the end of it they ask me: Would you like us to downgrade your service. Within 10 minutes of that we lose service. Luckily my laptop was on its own sim card. 

Enough is enough. Hours of my time wasted.
