Dealdirect questionable Business Practices

This company needs serious investigation or at least a review of their sales practices. Despite immediate cancellation once I started receiving emails congratulating me for signing up for a whole plethora of 'services' im not remotely interested in (the deal was for vouchers, not Uconnect SIM and magazine sub scriptions), and subsequent confirmation by email they company still tried debiting my account for R199, and I definitely did not authorise the Debi-check, , i definitely cancelled it (option 2). When I queried this, I was informed that there is a 20 working day cancellation period, also, not mentioned in the sales call. I will not pay them and I have received zero 'services' anyway. Im looking at possibilities to litigate this process if they continue trying to get subs especially since its clear they have a way of bypassing Debi-check, a massive concern. I'm addressing this with my bank too. I have all the correspondence from them just not the recording of the sales call.
