Quick Fit Winows

Although we are happy with the actual windows (so far), we were very disappointed in their salesperson. As anyone who works in construction or renovates, there is a time line that needs to be followed fairly closely.
We were quoted a date for these windows to be ready in 3 weeks. When we called for pick up the salesman told us they were not ready but he would check and call us back. We called back 3 times because he never called back. The salesman kept saying he would try to move up the completion date and then finally did not respond to calls.
It was finally the receptionist(?) who told us when the windows would be completed. They were supposed to be completed Oct4th but were not finished until Oct 21st.
There would have been absolutely no issue if the salesman had have just given us a realistic date and then had actually followed up like he said he would. This issue should not have been pushed onto someone else when he was the one that gave us a misleading date.
