Door handle replaced by shop (Whole Door Panel Done at time for $500) now two months later same exact problem. Why the hell is the only fix the whole panel!? Why make such a cheap part chevy?

While attempting to close the driver-side door, the handle broke completely loose on one side. Now, I am careful to pull on it to close the door because I don't know how much longer it can last like this. In order to fix it, I suppose I would need a whole new interior door panel which are not cheap. I've checked.
