I'm retired and need help cancelling my Comcast Business acct

I am a long time Comcast Business user and for the most part have had a positive experience. My wife and I are now retired and no longer need our Comcast Business account. I would like to cancel our service effective as soon as possible. We already have a separate residential internet service so we do not need to transfer to another service.

The internet is filled with posts from dissatisfied customers who get the runaround or no response from the Comcast Business support team when attempting to cancel or change service. I had positive experiences when dealing with the Comcast technical support teams, so I would expect something similar when cancelling my service. Please help me to have a positive experience so that I can continue to say positive things about the Comcast Business service. Thanks!
