Share Saver account

I was recently sold to the idea of opening and investing in a Share Saver account of which I did. I then did a test on it and invested R300 in the Account.

few Months down the line, I noticed that the share they have bought on my behalf without consulting with me had made 2% of my initial investment. I decided to sell the shares since they have made a profit and withdraw from the Share saver to my cheque account. After I did that, I saw that my initial investment has all of a sudden declined by close to 50%. When I spoke to the consultant it is then they now told me that they charge a "Brokerage fee" of R50 per share and they started explaining thing they did not tell me when they were selling me to the idea of the Share saver account.

If I was advised properly about the fees, I would not have "invested" in this and I just want the entire R300 back from you guys.
