Terrible service

I have an investment plan at Old Mutual. I havr requested to withdraw a portion of my investment. The prescibe waiting time was set at 15 working days, this has passed already on the 11 of June 2025. When I took it upon myself to enquire about this, I was told to wait another 24-48 hours, whick also expired on the 13th of June 2025. No communicatiin thus far at all from Old Mutual. The service I have received is terrible and the amount of time they said I must wait has passed so now why is it that this money belongs to me and for some reason I have very much difficulty getting it. This is a big joke. Old Mutual does not care about the customer or their needs. They keep telling me that all is good but nothing is paid out. Ref nr - CET***
