I am experiencing the same problem. I called and they told me it takes 24-72 hours to disable call waiting. What sense does it make to force people to have Call Waiting? It took me 6 different call-in events to Comcast's call center for someone to tell me that the Call Waiting feature cannot be disabled permanently until you turn it back on. I spent hours and their agents spend unnecessary hours as well. This company is very inefficient. Can you imagine the number of duplicate calls they receive every day? It has to cost them dearly. Beware of buying this stock! We need a forum outside of Comcast so others know about this.
