Unauthorised billing for the continuation of a FREE course, academy then offers 6 month free course then terminates my services.

I am disappointed that an institution that reminds you of a class 24 hours in advance and 1 hour in advance doesnt exercise that communication ability when a "free" course is about to be nilled. I find this to be dishonest (as they say its stipulated in the contract) but if I sign up for a free course at 4 weeks before it is billed the courteous thing is to ask if I would still like to continue as I will be billed. That was not the case - the billing information that is required at the beginning is so that you can sign up without it you cannot. Please dont request information fron students for a FREE course and then bill them and hide behind an ill written contract. Every reputable organisation will inform you if you are about to be billed as well as ask if youw ould like to continue as going further will incur a cost. How can I pay R399 for a free course without any modules and when I inquire my service is cancelled. I am highly unimpressed and want to take this up further. I would also like a refund as the contract is unclear - rather dont request details for billing until the 4 weeks has lapsed because I view this as a way to swindle students. Further I was then congratulated on finishing the course - I did not I only did 3 modules. I was entered into further modules after 4th module without my scheduling them and at times that seem to be generated by an alogorithm. Overall this is a dishonest practice - as much as I am happy with the course content the engagement with payment matters is appalling. Ont he day I was bil**** no one answerd the hpone, emails were not rep****, the whatsapp platform was not rep**** NOTHING at all. I have instituted a request for refund and I am not accepting the "contract"says its 4 weeks free then billing. Inform me of the billing and I would have told you no I do not want to be billed. Why was my service cancelled and the email I recieved about the contract matter offered me a free 6 month utlisation of the course platforms. What is that for?
