A clear sign of a declining relationship
It's just not possible for every single customer to be 100% happy with you all of the time.
One of the surest signs that a relationship is in decline, is one that might at first, seem rather odd.
When a relationship is heading for termination - the number of complaints offered and received declines.
When the complaints stop - the relationship is over.
The previously complaining person has moved on.
It takes time and effort to complain, you need to be emotionally invested in a brand or a company to care enough to go to the effort to formally make an official complaint.
It's just not possible for every single customer to be 100% happy with you all of the time.
Most businesses view complaints as a mark of failure, but it's a strong sign that your customer still cares enough to stick around and give you the feedback - hoping for improvement.
If you're not getting any complaints, it means that your customers are getting satisfaction elsewhere.
Sadly so many companies don't see it this way and simply respond to complaints with sterile legal, corporate jargon aimed to protect the company; rather than using this interaction as an opportunity to welcome the feedback and strengthen the bond that the issue has created.
Complaints are a good thing - value them, track them, take them seriously.
