6SigmaStudy — This company is definitely fake!
This company is definitely fake! I found 6SigmaStudy and thought it was a great idea. So I signed up, paid some money and after that received a message with my login and password info. But I could not log into my account and when I clicked the "forgot password" it said that my email was not registered. That was strange, because these people took my money and even sent me a message. Tried to contact customer service, but there was no response.
