Fidelity National Financial review: Plumbing issue

Claim Z28938, Service Work Order Number 8485380
I called Fidelity National Home Warranty to fix a clogged waterline that services my main guest bathroom toilet. They assigned the repair to Advance Plumbing and Rooter Services to fix the issue. After 2 visits to the house and a big new hole in my wall, the problem has not been resolved. In fact the plug in the line has now moved to the outside wall hose bib.
After not hearing from anyone regarding what was happening Advance Plumbing told me when I called them, Fidelity was not going to authorize the completion of the water line replacement/repair. Their explanation was "plugged water lines were not covered by the policy. Now I am stuck with a hole in the wall from the plumber and a plugged hose bib.
Why was the work authorized in the first two plumber visits and now its not? I told everyone up front it was a plugged water line. I even told them how to back flush and unclog the line, which the plumber did not do on either visits. The plumber concluded it after the second visit, the job would take a new water line to be installed from the attic to the toilet to restore the water line service to the toilet, and probably more holes in the walls.
Why was this service call authorized when up front they were told by me in the beginning that it was a clogged water service line?
I believe that I am due a completion of the job, a flushing of my water lines to unclog (now) the hose bib, my walls patched up, resurfaced to match the existing stucco texture, and the patch painted to match my existing wall color. I do have the paint on hand so no one has to worry about matching colors.
I am f_king mad about this service. The incomplete product, and the total inability to talk to anyone about this. I did get in touch with a service call manager and he was the one who placed me on hold and left me hanging for over 3 hours then then dropped the call.
I have attached two photos with this submission. The first is the hole in my wall with just the stucco cut out sitting with in it. The second of my hose bib turned full one.
I want answers and if needed heads to roll.
