Unresolved Refund for Deductions After Policy Closure

I am writing to formally express my dissatisfaction with how Old Mutual has handled the refund of deductions taken from my account after my policy was already closed. Since discovering the issue, I visited the branch in person to resolve it and submitted proof that the deductions had occurred. The branch confirmed the relevant documents were sent to head office. Despite this, four months later, I still have not received my refund. I have been in ongoing email correspondence with a complaints manager, providing all requested documentation. However, I keep being asked to resend documents that have already been submitted by their own consultant — which feels like a delaying tactic rather than a genuine effort to resolve the matter. This experience has seriously shaken my confidence in Old Mutual. I currently hold a life cover policy with them, paying premiums every month. If a straightforward refund cannot be resolved in over four months, I am left questioning how a life cover claim — meant to support my family when I'm no longer here — would be handled. I am requesting an urgent resolution to this refund, along with a clear explanation for the repeated delays.
