Dragging to Refund it's been now 190 days plus

I have paid for a subject which I have not yet sign any agreement or procedure. And decided to cancel as I am capable of studying it on my own. I did send all the required documents that they needed at Boksburg Damelin in order for them to send it to head office in Durban for refund. They only send it after 90 days to Durban. I phoned Head office in Durban they told me it will also take 90 days on their side to refund me. 100 days has passed already. I phoned the Head office on 09.10.2017 and they told me that they do not have a date when they will be able to refund me. I spoke to a lady and she just told me I must ask her manager as they still have not send the documents to there finance department for refund and she does not know either when they will send it. the email address she gave me of her manager I am not sure if it was even the correct address.

I am in desperate need of that money as it is holding up my education which I would like to register. I wanted to write my exam in November but was unable to register as Damelin is messing me around with my refund.
