This is the difference between doing business with customers and taking advantage of customers.
Concerning Customer Service, doing business with customers in an ethical and gratefully way is to enter the business with the true intention of providing a good service at the best price, so that customers feel that we, their service providers, understand their needs and that we are their allies.
Taking advantage of customers, selfishly and inconsiderately, is to bleed customers for years and years, making customers believe that there is true friendship and consideration towards them, and only improve prices when that customer finds another provider that offers the same service, with better Quality and at a better price.
