xFi Complete - wall to wall coverage

I am paying for the xFi complete option, which states that I should have wall-to-wall coverage with an xFi pod.  I was told that it would be a maximum of 14 days for the system to determine if I need an xFi pod. Tomorrow will be 21 days since my account has been active and I still have not received notice of my status. I cannot even connect to devices at the one end of my home. I am unable to utilize my workroom because, at times, I cannot even see the wi-fi network from that space. I need the pod to have wall-to-wall wi-fi. Trying to get a hold of a real person to help me is a joke. Your system just gives you the run-around with anything that is a custom question.  This, tied in with the multitude of incorrect information that I have been given as well as being told that I can just buy a pod to fix the issue (I am already paying for a service that should take care of this) has gotten me so frustrated with xfinity that my hands are almost shaking when I am typing this.

I need this fixed.
