My driver door handle the part where the lock is broke for some reason? Why?

What is your question?

It broke from the inside and he outside which I have will not let me glue it on I tried. The Nissan people here in Lake City, FL want to charge me 65.00 to glue it on or replace the whole door handle the door still opens, but it leaks where he broke is missing now. I have a warranty that I purchased from Mastercraft which is a company that says the warranty won't pay for the broke part. Does Nissan warranty broke door handle?
