Dissapointed and angry

I joined a dream maker policy in December 2012 and was promised good returns. Somewhere along the years i asked them if i can increase it and they agreed, to my surprise i got a notification that increament will result in my policy being pushed up with another 5 years. Ok i queried and they rectified it because their consultant did not explain to me. Now today is the maturity date and im told i will get my sorry returns within 10 working days. I called on tuesday and the agent told me to submit a bank statement to the nearest branch and yet again did not explain the 10 days clause. Im so, so disappointed by this and will never invest anything ever again with Nedbank.
