Verdun Windows And Doors

I ordered windows and doors in Feb 2018. The windows were installed in July (almost 2 months later than initially promised), however we had issues with 4 out of the 9 windows. (No frosting on bathroom windows, cracked sash, missing dryer vent). 2 of those issues have been addressed and they just told me the remaining two are ready for installation (Nov 2018).

The doors have been ready for installation since August, but they are choosing to install windows instead. I am still waiting for a final date. I have asked for a discount on the total order, but Verdun has refused saying "we are all in the same boat". I disagree.
