Having worked in the customer service field in the past, let me see if I can break down this exchange.
A.) Customer doesn't experience the desired result of a product or service, most likely due to customer error.
B.) Since, in the entire history of commerce, no customer has ever been able to admit making a mistake, customer blames the service provider, even though the product or service works fine for every other customer.
C.) Customer then contacts the provider, complaining to, harassing, talking down to and generally belittling the customer service rep for something that was likely the customer's fault to begin with. (Insisting that they confirm to you that the process is as stated, because you want it documented so you can throw it back in their company's face the next time you don't get your way is a bit demeaning. You sound like a teacher looking over CS' shoulder as you force them to write "I will not shoot spitballs in class." 100 times on the chalkboard.)
D.) CS does their job by referring you to the readily available online documents so you can find the answer on your own in the future, which will reduce nitpicky future requests, thereby speeding up the entire CS process, which is beneficial to everybody. The other reason CS does this is because their own documents are the final word, and if they just give you a "yes, you're doing it correctly", you can throw it back in their faces if the steps you reported taking are less than accurate.
E.) Not satisfied with CS' refusal to bend over backward to accommodate your every little whim, you then take to the forums to bash the job CS is doing, confident that every other customer will race to your defense and support you, because after all, you're the customer, how can you be wrong about anything?
Looks to me like the same exchange that takes place 1,000 times per day, every day, in every customer service department in the world. In other words, WIS is doing their job exactly as they should as far as Customer Service goes. And as a customer, you're being a pain in the butt. So both sides are playing their roles to perfection, what's the problem?
Remember, the phrase "the customer is always right" was only coined because it sounds better than "this guy's a jackass, but do what he asks because we need his money".
