Fail to cancell policy 3 months

Cib failed to cancell my insurance policy, now 3 months and they still take premiums via debitorder. Their personel got no urgency to sort out my problem. They owe me R2500.22 for premiums they took after my request to cancell policy. This no effort was done to refund me my premiums. Now after 3 months my patience is running out. My broker at Absa Cib could not set up a meeting with me. Could only get a meeting with him in a week time. Upon emails send. Reply was that current brokers don't know what they are doing. What happened with service delivery. I would expect assistance in getting my problem solved.
