Poor Service

We were invited to the presentation which we attended sometime in Sep 2020 , After the presentation we were still skeptical to take the offer but was told that if we did not take the offer on that day we wouldn't get the same rate again should we decide to join afterwards. At the presentation we were told that we need to make a upfront payment of about R5000 then there will be a debit order for R1300 for the next year. I called the call center yesterday to find out when will be the last debit order, I was advised then that it will be in August 2021 but thereafter will be a monthly fee of R376, we were not told about this fee at the presentation. I emailed the company to cancel this contract and get a refund which is being refused, The consultant now says a email was sent after the presentation and we should have read the document, Yes a email was sent but after all the hype at the presentation we took for granted that what we were told is what we signed up for . The customer service is so poor, The consultant refuses to address the matter and just claims there's no refund due as per contract - This go's against "treating the customer fairly " The presentation is misleading , Can someone at the company assist with this and not use the contract as an excuse to not refund the money - misleading the consumer at the presentation then send a document with small print is not ethical business practice
