Sharetrackin ****- False agreement

I was contacted by Belinda on a Saturday that they have a very good offer for stock exchange shares opportunity. Andre arrived on Monday afternoon for presentation that lasted over an hour with some graphs and calculations promising I could turn over the money invested in my shop to be millions of rands in 5 years. I told the guy it is a good idea and interested but would like to go home and discuss with my partner and also to read the contract. He insisted I sign in order for them to make reservation for me which will make things easier when I am ready not knowing he cunningly lured me into committing myself and took R4,000 from my account. I called in the second day to cancel whatever reservation made for the lady to tell me I have been registered and nothing can be done but I protested that the guy told me it was only reservation and she said NO NO NO. Now, I asked for the refund and the lady said I will pay R2,950 for cancelling that she did me a favour by cancelling the contract. Very unprofessional and ******** that uses contract agreement to rob people of their hard earned money. Doom will befall you soon.
