Zager Windows

We got windows put in by Zager Windows on April 11, 2022. They said they'd come back after the check-up to put in the strips that cover the screws. We called them on April 15th to set it up. They said they had a lot of them to do and they'd do it when they had time. It's been a month now and it still hasn't been done. We've called them every week to get it done and we keep getting the same answer. On May 5th, when we talked to them, they said Mr. Z. was going to do it. When we asked when we'd hear from him, they said probably tomorrow. That was a week ago and we haven't heard anything. We can't put the furniture back in its place until they finish the windows.
