Innovative solution​

Dr. Platter,

I need a powerful, innovative solution.  I am a manager of a supply company that provides materials for commercial construction projects.  I have been with the company five years and enjoy my job most days.  The problem I’m having is that sometimes the clients complain about the product even when it is exactly what they ordered.  I have a large territory and cannot always give the client the individualized attention they need.  The sales people and installers have far more contact with the clients than I.   During the times when I have had the time to visit an unhappy client, the problem is usually an easy one to resolve.  I don’t want to complain to the owners because they might I can’t handle the job.  However, I know that if clients continue to complain, that will reflect badly on me as well.  What advice do you have?
