Customer complaints provide amazing feedback that allows a brand to reinvent itself, re-position itself and stay relevant, says Femi Adebanji, research head at the Service Excellence Institute. Research shows that only 4% of customers will complain following a bad experience, while 96% will not voice a complaint.
Furthermore, while customers might not voice a complaint following a bad service experience, 91% will not come back and would rather do business with competitors.
