Capitec is refusing to refund my extra premium

Capitec Bank is taking me for a ride. . I have a funeral policy with Capitec and I paid my first premium at the end of June via debit order on my Capitec account. I was worried as I did not want to miss the premium. I made a manual payment on the app and the debit order still went through. As a result I ended up paying 2 premiums at the end of June. The payments went through on 29 and 30 June, R379.55.

Unfortunately I cannot reverse the debit order. I have tried to get help from Capitec customer care. They paid the R379.55 back into my account yesterday, 10 July only to deduct it again on the same day!!!

Capitec please don't be ******. Please pay my R379.55 back into my account today!!! or I am going to cancel the funeral policy the and report to the banking Ombudsman and Insurance Ombudsman!!
