False adverti*****t/****

When I joined Shaw academy I got a phone call from someone who works there and told me that my number was on promotion so I was going to get the first month completely free including course content and everything. This phone call was followed up with an email which said a number of times that I was going to get the course and course content for free as the first 4 weeks were completely free. I thought that the customer service was really good and had few doubts about them. However, after registering for a course R500 was deducted from my account without my consent and they are refusing to refund it and have now stopped replying to my emails. I cancelled my subscription immediately and so I don’t even have access to the content that I bought.
