MSI is it just another ****?

I also got a call from someone at MSI. The gentleman told me that they have a system that they offer to help me invest in shares and that they guarantee between 25% and 40% return in six months. He wanted me to agree to speak to a consultant that would come and see me. I suggested that I would rather come to their offices and asked for their address. He said that he does not know their address as he has only been in Cape Town for two months but if I am not interested in meeting with someone at my office that I am clearly not interested in what they have to offer. He clearly wanted to end the call but I kept him on the phone suggesting that MSI is starting to sound like a ****. He got somewhat upset when i asked him for more info on the company and its people and terminated the call.<br> <br> If it sounds to good to be true it usually is. In hindsight their offer might be that they guarantee that you will only be left with 25 - 40% of your investment after six months?
