Zeigler contracting inc

I am constructing a house in Cape Coral, Florida. I have contracted Zeigler Contracting Inc. for the masonry work and they are yet to complete the job as paid for. I have requested that they install the foyer window sill numerous times (11-2-2015, 11-17-2015, 12-7-2015, 12-11-2015, 12-14-2015). At this time they have not responded to my requests. Zeigler Contracting Inc. have been paid in full for this project and I would expect that they would complete the job as requested. The other work that they have completed appears to be good workmanship and approved. The fact of the matter is, ONCE THEY WERE PAID IN FULL THEY WILL NOT RETURN TO COMPLETE THE JOB. Lesson learned. Per your religious scripture on your website you believe that you are a sinner, apparently that is true. When you are paid for a service and you do not provide that service that is a sin. I would not refer Zeigler Contracting Inc.
