Still no study material/no positive feedback

We've paid a deposit and registration fee in December 2014 for my son JJ Bezuidenhout, to do Gr10. Still not received study material, May 2015. We've made numerous calls and forwarded mails. Only to receive empty promises. We've notified Intec via email and completed a de-register form to cancel in March, as we are not happy with the service. Still they deduct the monthly debit amount and still there is no study material or ANY FEEDBACK and on requests we're only told that the money will be deducted until THEY'VE decided when to cancel!
