application to surrender a Dream maker investment

I am very disappointed with Nedbank/Nedgroup life for not being clear when it comes to a dream maker. I have opened a dream maker investment with Nedbank for a period of 5 years, it is now matured but I can not get my funds becaude I stopped a debit order for the investment and now I can only get my fundsonly by April 2019. Why are we not told these things early and never mentioned only when we have to get what is due to us, this is absolutely rediculous and disappointing. You wait for weeks and after calling them they tell you that they don't have your docs and after sending your docs you are disappointed by their response. When you take on an investments its because you have certain dreams and goals to fulfil but now after waiting five years you get disappointed.
