Dishonesty and incompetence

So I registered for Facilitator 3 months back and I was assisted by Belinda which she told me that I can deposit 2000 to get my study material and I did exactly that but I haven't received anything from them instead I was asked to pay 850 the following month.

I don't recommend anyone registerring with them and I will be a great pleasure if I can be refunded, I want my money back.
