I keep this little greeting card on my desk every day, listing the facts about customer service. It must be over a decade old now, but it still rings true:
It costs 6x more to attract a new customer than it does to retain an existing one.
A typical dissatisfied customer will tell 8-10 people about their problem. ( Here I would imagine that thanks to internet that number is now in the hundreds and thousands, for example, Kevin Smith’s tweet about getting booted off Suthwest Airlines for being too fat)
Seven out of ten complaining customers will stay with you if you resolve the complaint in their favor.
If you resolve the trouble on the spot, 95% of customers will do business again.
Of customers that quit, 68% do so because of an indifferent attitude from the company or the person at the point of contact/sale.
I dumped my cable company in part because of shoddy service. I dumped my ISP because they were incompetent people and the phone persons refused to put down the stupid irrelvant script they had been issued to just talk to me about my specific issue. Based on what I see int he linked article, cable companies know they aer bleeding customers from shoddy service, but must figure they make up for it in volume of new fish that sign on every month.
