Dissatisfied client

I've got an investment with old mutual that I've been trying to cancel due to the fact that 2 years ago I lost my job and now struggling to make ends meet. I've been told several times that there's restrictions to the investment. I've gone through the contract and and it states that should I wish to do so I can send an email with my reference number, I did that but up to now I haven't heard a thing from them. At this point I did not mind canceling the investment and let them take whatever penalty fee they would charge if I decided to cancel before the actual date. How am I to survive up until the year 2023 without a job and without money. Even worse suffering when you have money tied up somewhere where people will tell you it's inaccessible. I've had several branch visits to try and get help regarding this matter, however to date I haven't had any help... I'm really disappointed to have such an experience from such a reputable company. Should I ever wish to make any form of an investment in future, Old mutual is definitely not an option.
