Comcast, grrr.....

I got my first bill from Comcast since dropping their cable TV service today... and, although it's supposedly for next month's service, and although they indicate elsewhere that I'm only signed up for Internet at this point, there's still a line item for TV service on the bill. On that same bill, there's a line about "we're here for you 24/7 at 1-800-COMCAST"... but if you call and work your way through to "billing inquiries", they say that they're closed and normal business hours blah blah blah... I guess I'll try again tomorrow, but how can something as simple as changing your service plan be such a pain to get right the first time?
