It's also a fact that some people might to some degree be fundamentally intellectually challenged, so that really doesn't prove or shed light on anything. Besides which, your personal sample of one isn't representative of the hundreds of thousands (Or more) of sales, inquiries and RMAs handled by Corsair over the course of any given year. I'm not saying it can't happen, because every company these days has to some extent limited the quality of their customer service response by using poorly trained or non-english speaking help desk people, but overall, this would be an uncommon occurrence and a follow up contact or contact through their forums would likely clear things up for most people.
If in fact the support person you dealt with handled your case incorrectly, and the product was still in warranty, it would have been prudent to try and escalate the response. Sometimes we have to do this with ALL companies, including ASUS, MSI, EVGA, and others. It happens. Just because you get an idiot support agent doesn't mean the company itself doesn't back it's products.
