Sanlam Sky poor service and not paying refund on time

Sanlam Sky is the worst. I had a policy with them which I cancelled in July 2022, they are still debiting on payslip to date. The refund for July was received in Augut after I had to complete the refund form. I was also informed that they can not cancel the stop order immediately and that it will take them up to 3 months to stop debiting. So in August the call centre agent I spoke with said the the refund will be automated and I got the refund on the 8 September of the following month. Now I have been calling them for the refund for September and they saying it has not been done. The date is the 10th and a refund for the 26 September has not been payout
