just to clarify, are you saying that lower paid staff can give incorrect answers....and not have it reflect the company they work for?As someone who's worked in retail/CSR/service positions, people like you are literally the worse. You are the type that will jump down on the lowest paying employee's throat (MSI rep in this case) the second something doesn't get your way. You are literally the "Can I speak with your manager type." This is regardless of how right you are or how much control the employee have.
Remember, the pitch forks are out for the multi million dollar company, not the team member that wrote the response.
If they didn't know the answer, support staff should have simply replied "Unfortunately I do not have an answer for that question", or supported the customer in asking another team member for more information.
Then again, we don't know. There could big a massive white board message that says "No Zen 2 support for x370/B350/A320", however, that is very speculative.
MSI has made a mistake, and have followed it up in this article. I'm sure they'll have a word to the support team and implement a better procedure for when customers ask about future features, and they do not know the answer.
