Old mutual won't pay out cancelled investment

I placed a cancellation of my investment with old mutual on the 16th of January 2018. The cancellation was received and I was told I will be paid on the 8th of February 2018. I've been calling each week to check if the date still stands and have been told it is. I called on Monday the 5th to enquire about the 8th being the final date and was told it is. Now today when the money is supposed to have been paid out to me they are telling me that I still have to wait 5 more working days. Why? After wasting my airtime calling for the past 2 weeks. Please old mutual I need my money paid ASAP as I have other commitments to fulfil. Policy number ********** 8 unique tracking number: CSCCA ********** 1
