*****, who wont pay me back my full interest on my investment.

In 2002 I took out an investment with Assupol life. 2011 I lost my job and stopped contribution to the investment. Prior to that I made 2 withdrawals to the total of about R6 000. Assupol has now send me a statement reflecting 2 figures, 1 - R20 500 and the other one R7 300 which is money that was reinvested for 2 years and expired in 2019 October. When I visited their branch in Mitchell's plain Cape Town, a young black guy assist me and told me that unfortunately the only money due to me is only the R7000. I disputed that with him and he told me that he would escalate the matter which will take 21 working days for Assupol to back to him, in the meantime I am in need of the money. I was told i could access the money within 48 hours, now I must wait 21 working days. I then asked the guy if that is the case where is my interest of the money i then had as a balance over the years? The guy couldn't answer me. I want my money with immediate effect or we will meet in court. H e refuses that Assupol sent me a statement he says their system doesn't have such a letter on record for me. Talk about incompetency.
