Best Double Hung Window Installation And Replacement in Phoenix AZ

I sent them pictures of a broken mirror which I wanted to replace the glass in. They said they could do it, so I drove 45 minutes to drop it off. I got an email back later saying that they were having trouble finding a backing that would work. I made a suggestion that I thought might work, but I never heard back from them. After a month went by, I sent another email. Two days later I got an email back that they can't fix the mirror. I totally understand if they can't do it, but its not great customer service.
