There are always at least 2 sides to a story and a witch hunts work both ways. Anyone could be next in the sights of someone seeking revenge or just to cancel someone or something.
Unvetted stories on a forum regarding customer service are not always the best source of information on this subject, but they are very predictable.
What kind of customer are you? The customer service you get depends on you and you do not know what is taking place on the other end of a conversation unless you are told. Customers with bad manners, or who seem to have endless insults, or who don't "listen" may not get the customer service or results they are seeking. It could be, when you tell a company you will never buy from them them there is a sigh of relief.
There are customers who buy fake, look-a-like, or counterfeit products who then expects the real company to support the product. According to a GAO (US gov 2008 study) searching for the absolute best price on a product is likely to lead a customer to a fake, look-a-like, or counterfeit product at least 43% of the time.
On the other hand, there are good and bad people and companies in all industries and walks of life.
