Worst experience. ************ and not reasonable.

I registered for electrical engineering in July, I paid R600 registration. They send me 1 text book . The bursary I app**** for did not approve my application, so I asked to cancel my studies at oxbridge academy. I was told that the matter was taken to the attorneys to review cancelation but I have been getting threats from NBR risk solutions, Pearl and Cindy. They are threatening my credit score and said I have 48 hours to pay or else .... they send me a letter of demand that I should pay R14600. Please help urgently.
