What is "customer defection rate"?
Every business suffers from customer defection – many services businesses have double-digit defection. Let’s say a business has an annual defection rate of 10% – if it had 100 total customers, then at the end of year 1 it would only have 90 left ie. 100 customers * 10%). At the end of the second year, the business would only have 81 customers left (90 customers * 10%)

This is why on the spot customer feedback is required so that an unhappy customer will alert the business to the problem, thus allowing the business to fix the issue, even recover that unhappy customer
