Company is no longer in business Need to cancel service, ready for Comcast nightmare I'm sure

My company has not been in business starting 2016. As I was tying up loose ends, realized that I'm still getting Comcast Business Internet bills. I need to cancel this service. If Comcast checks my internet usage for 2016, it would be 0. I need to know what I can do to amicably resolve this with Comcast or is my best bet to just stop paying the bill and have Comcast go after the corporation that has 0 assets. I've been a loyal Comcast subscriber my whole life, but based on what I've read they are especially vicious with Business customers.
