    Six Sigma is all about focusing on customers. Lean Sigma Corporation is providing courses and materials for Six Sigma and they are not even practicing the basics of customer service. I purchased the PowerPoint training materials and found out it was password-protected!?! This is no indication at all in the product description that this is the case. Moreover, I have sent many emails without any reply. I would like to request a refund as this product is useless if it is password protected. But I cannot as there is no reply. Additionally, I suggest that new customers to stay away from this product and this company. They are the worst in the market.

    I despise any company w/o a phone number.
