replace window pane

The first time my husband took a window in, he had to wait as the owner showed up late, but did get the job done. Almost one week later we had another incident with another broken pane. Several times during the week my husband called but could get no answer. He decided to just take the window to the place of business this morning, 10/12 but no one was there. My husband called and was told someone would be there soon. So my son and husband waited about 2 hours. No one showed up. They went to Home Depot to get something and called again. They were told someone would be there in fifteen minutes. My husband drove back to the place of business and waited 45 minutes. No one showed up. When he tried to call the phone number, no one answered. Frustrated he called me at home and I started making calls. If this is the way someone conducts business, it's a pretty poor way. My husband is now on his way to Sun Glass and Mirror. It is now almost 2pm, so he has wasted his whole day off waiting on the Window Doctor. Shame.
