Xfinity Internet support is terrible .............I just waited 2 hours of my life and got nowhere

First let me start off with, when it comes to computers, switches, routers and gateways ... I know what I am doing .... over the last two weeks I am experiencing random internet outages which also causes my Xfinity range extenders to go offline ..... ,  this morning, when I checked the gateway logs  I can see where the " UPTIME " was only 5 hours which would correspond to the time the internet went down, called Xfinity today and for two hours of my life I was told that there was nothing wrong and they had me reboot the gateway and the pods all of which i had done before calling ..... while I was on the phone with the agent the pods lost connectivity. I kept asking to speak with a second level tech and they would not put me thru to someone that knew what they were talking about .....  when I was asked to reboot the gateway and pods a second time .... finally lost patience and demanded to speak to a supervisor ......which i was told she would call me back in two hours .....  Then to make matters worse, I am moving to a new home in two weeks and i have a Xfinity install scheduled, the agent told me that in order to dispatch someone to my current residence they would have to cancel my install 

This is just terrible customer service ......can someone call me who knows what they are doing ....
