Old Mutual refuses me to disinvest

A few years ago I took an investment policy with Old Mutual. And when I wanted to disinvest Old Mutual is refusing saying in terms of the Terms and Conditions of this investor I can neither withdraw or withdraw any funds from it unless the amount is below a certain amount.

They said I had signed documents to this effect but failed to provide such documents. At some point they said they had emailed me but the email address they said they had used was not mine. Early this year I approached the Ombudsman but to date the Ombudsman has not been able to finalize this matter. Last week I wrote to the Ombudsman requesting progress, but I have not heard anything from them. At some point the Ombudsman took the side of Old Mutual saying that I had signed the documents. But when I asked for those documents they could not prove me with them. I also brought to the Ombud’s attention the email quoted was not mine, which meant that I never received the documents. Both the Ombudsman and Old Mutual are not concerned about the fact that I need this matter to be finalised. And the Ombudsman seems to be very gentle and treats the Ombudsman more favorably than me, hence the delay from Old Mutual.
