I have heard this before about marcus evans rip off circling around the internet and paid little attention to it. There is this saying that goes, "you cannot please everybody" so what this means to me is that no matter what or the business do their best service to the customers, there are those that are unsatisfied and unhappy of the outcome so they file complaints. While there are companies also who do a bad job that will put customers in a position to complain and file a dispute.
If a company receives a complaint then what they should do is settle it so to retain their good reputation and could gain referral to other people through words by mouth because the norm is, if a customer is happy with one's company then he or she is more likely to spread the word to her friends, right? I have never known there is such company like Marcus Evans that handle customers complaint in a strategic and effective ways. The company's conference division have run a range of events focuing on best practice and effective strategies for dealing with complaints and marcus evans rip off protection.
