Firstly, Comcast has no business why he wants to cancel. He might want to cancel because he landed a tails on a coin flip on a Tuesday, and it shouldn't matter.

Secondly, with such strongly hostile customer service representatives the more you speak that's more ammo you're giving them to argue without cancelling the contract. If you say, 'customer service is poor' there's a high chance that CSR going to pull up records saying that "You called us X times with Y and Z complaints and we have responded to them within 48 hours. That's well within our metrics" or some bs like that. Talking to hostile CSRs is akin to talking to the cops - don't speak more than you have to.
