I'm really glad that that excuse made the process so painless for you, but I do have a cautionary tale about that.
Two years ago, I called them and tried cancelling my service because, like you, I was moving and my new landlord was providing Comcast to me as a part of my lease agreement. Despite my insistence that my landlord already had an account setup for me at my new house, I was kept on the phone for 30 minutes and the representative insisted that it would be beneficial for me to have my own account/service at my new house in addition to the line that's already there, and that I should just transfer my service. You can imagine how frustrated and furious that conversation made me.
I don't mean to deter people from using that excuse, because it still honestly seems like that should be the easiest way to cancel your account, but I do want people to bear in mind that it all depends on the representative you speak with.
I've canceled Comcast service several times now. I've got a pretty good routine down. Basically you just preference the call with "I'm canceling my contract with Comcast today. There is no discount, inventive, or conversation that you can give me that will convince me not to cancel. This cancelation needs to take less than 5 minutes and the phone call is being recorded".
Comcast customer service does seem to be much better now than it used to be. Possibly they got the hint that they were pissing everybody off enough to get voted into the top of the list for worst companies in the U.S. year after year after year.
