Frustrated retrenchenched customer

I bought Unit trust with Old mutual in January of 2018 with an Idea that the very same money will be of help to me in the future. I worked for a an NGO which didn't provide for pension fund but only gave an allowance towards your pension and I took the initiative to put that money away so that it will help me in future I needed it. I have been recently retrenched and i call Old mutual to let them know that i had lost my job and was told that I couldn't have access that amount of money because it's the retirement annuity which I can only access when I'm 55 years old. It is frustrating for me to hear that because that money is being of any help to me right now the consultant told me I could withdraw the money if it less than R7000 but since it's more than that I cannot which is actually ridiculous to me because it means there is an option to withdraw after all. It's just the amount you wanna withdraw

Which means I am stick with these useless company and their ridiculous laws for another 15 years. They wanna make money using my money but I will be gaining nothing in the end the money is just gonna sit there being available to to do whatever business with it while I suffer.
