Request for a cancelation and a refund on premiums debited.

I writting to ask for assistance for a cancelation and a refund on the premiums that were debited by Absa activate insurance on my account after I have sent a request to to cancel the insurance . I have sold the vehicle 3 months ago and have advised that I'm covered with another insurance company on the new vehicle and I'm now being double debited. Could you please look into this matter as I was told that the payment instruction was sent to the head office on the 26th of June 2025 until today I have not received my money back. Thanking you in advance.
