Disgruntle client from liberty Investment standard bank

I was called by the standard bank to come and see their financial advisor ,she advised me to put an amount of 100k for 5yrs investment and did the calculation that if the interest rate were above 21-23%by the the time of maturity possible return could be anything above 200k .Our agreement was on maturity the money should be deposited at my standard bank cheque account. To my suprise maturity date passed and 2years plus couple of months were added to my 5yrs and the money was never deposited to my account until one of their consultant phoned me enquiring about my portfolio that has been neglected and my money was now decreasing from 101k to 94k .I withdraw my funds with the help of the new consultant .I lodge a complaint but the person who was on the case told me that the investment doesn’t state the maturity date only the minimum years of investment is 5yrs minimum. I was ****ed that I put up my money for 7yrs plus for better interest return in order my money decreased dismally and years that I have put on without gaining a dime or cent from it .If I could have left my money in 32 notice for all those years I could have earned a better interest ,without Liberty chowing my money.
