Pay back my money, Old Mutual

I've took out a flexible investment plan with old mutual in August 2018. Due to the lack of performance and the economic status in our country, I've decided to cancel the plan and disinvest 100% of my money, which I did on the 16th of October 2018. On the 26th of October 2018 I was informed about a cool-off period, and only when I followed up on the disinvestment. They said that I must put it in writing if i'm not going to make use of it, which i did and i emailed it to them the same day. However this changed nothing, as weeks passed before anything happened. I followed up again, this time I was informed of a lapse date of 27 November, which make no sense if I informed them that I'm not using the cool-off period. On the 28th of November I send them an email again, which they rep**** to after 2 days. Currently 49 days has passed since the cancelation and disinvestment request and i have received my money back. These people does not perform any professional s****s and integrity to refund my money, it belongs to me after all.
