I happen to open my windows downstairs the other day and when I went to close and lock them they would not lock. I called and no one returned my call.
I called again and it was almost 5 pm and then Zi got the call. I told them the problem and he said someone would contact me. Well that was 3 days ago.
This is the second time they did not lock. After they were installed in 2012 or 2013 not long after I had two that would not lock.
