Contract expired, non-existent "Customer Service"

My 3 year contract for internet only has expired and the new bill is due July 2nd.  I have been trying for about 2 hours to get someone on the phone or use the website to try to get another contract deal.  I've been with comcast/xfinity since about 2000 and this has to be about the most frustrated I have ever been.  Customer Service seems to be non-existent in the company now.  Everything is automated AI and the idiotic "keyboard clicking" sound on their help line has to be one the most ridiculous things in existence.  Would anyone under 80 years old REALLY THINK someone is on the other end typing?  It is true that they do not care about existing customers and only give the "best deals" to NEW customers.  I'll never understand this practice, but I guess part of it is that they expect to sucker new people in and hope that when the time comes, they don't bother with trying to get another deal and just let auto pay continue to pay the new amount when their contract expires.  It was hard enough justifying what I was paying in the contract so with the increase ($30 a month!), I need other options.  I will even drop the service level to a lower speed if that's what it takes.

Also, If I would get into another contract does anyone know if I have to pay the amount of the current bill or if it will switch to a new rate (if or when I would get a hold of someone).  Thanks for any help.
