Bad investment

I had an investment at Sanlam for 20 years. It is a retirement annuaty. My money did not grow interest wise at all and i barely get out what i put in. I stopped my annuity prematurely because of that and now i had to pay fee for that as well. I have been waiting for my payout for more than a month now although they said 15 to 20 working days. My broker who receives a commission for advice did not come back to me at all. So overall i am very disappointed in Sanlam.
