Bought new service and no one could help me to install, plus costomer service terrible.

I spent more than 5 hours over the chat trying to setup my new internet, detail: I was just updating the existing plan for new one, they disconnect the existing one and I'm 5 days with no internet, at costomer service over chat, the agents keep changing the attendant, every 2 minutes a new one comes and start over the process, asking the previous questions, asking confirmations and, again switch to another agent, that star over the process, and again, again, and again. I have all the conversations to prove that. If was not enough, in one of the days when I was trying to schedule a technician to come, the agent, with no permission updated my service for a expansive one, that I never asked for, and left the conversation, and I received a email with the updated non authorized changes. Sadly Comcast becomes a scam company with a terrible costomer service, I feel like when someone call you trying to scam you. So sad and terrible.
