Need advise - we have one customer who is literally next door to us and expresses his concerns / complaints / grievance on a daily basis by all modes of communication like email, telephonic call and in writing. They have in fact instructed our Customer Service Manager to see them everyday so that they can give their "valuable" comments. They have also granted partial access to some of our employees so that they need not make "Visitor's Pass" when they come everyday.
Now, the problem is, this customer is not "Quality System" conscious and complains for any small issues that may not be really valid enough.
I need comments from you how to handle all these complaints ? I know that if we go by the definition of ISO 10002, all modes of customer complaints need to be tracked.
Any suggestions on how to track these complaints ?
