"You can please some of the people all of the time, you can please all of the people some of the time, but you can't please all of the people all of the time."
Although later adapted by Abraham Lincoln, those words were spoken by a 15th century English poet named John Lydgate. They have survived for centuries as the Rosetta Stone for understanding why no matter how good your customer service is, you will always have some customers that you just cannot satisfy. It is just a natural component of doing business.
While it is always better to resolve conflicts on a personal level and without intervention, when it becomes obvious that further attempts will lead nowhere yet consume more time from your business than you can afford, that is when outsourcing to professionals makes the most sense. And when you can do that for a fraction of the cost of handling it internally, it makes no sense not to.
Trust the professionals at net-ARB to handle your most difficult customer service disputes courteously, fairly and economically, freeing you to concentrate your limited resources to the real challenges of improving your business.
