Rosalind in Oliver

I paid over $5000.00 for a front door through my building contractor in November 2015. The door took FOREVER to be fabricated and delivered in March 2016, but the interior casing was cut incorrectly. It's now August 2016, and we still don't have an interior casing. Our contractor has called repeatedly for the correct casing and they get NO answers. I WANT this settled NOW!
