I was to take a course in Six-Sigma Green Belt back in December of 2015. I received an email day before the course was to run that it was cancelled and I would automatically be registered in a February 2016 instead. I could not attend at that time and asked for a refund. I received themost polite run-around and for several weeks could not get Knowledgehut to refund my tuition(and they assured me that a refund was forthcoming).
Finally, I had to resort to asking my bank to intervene and they were good enough to refund my tuition. Knowledgehut lacks ethics and I would advise anyone who is thinking of doing business with them to reconsider where they spend their money.
