FNB keeps *****ing my money

On 04.01.2021 i had a phone call from one of FNB's consultants asking me when will there be money in my account for a debit order - "DEATH PROTECTION PLAN" I was on the phone with the consultant for 34 minutes and 21 seconds and i told the consultant that i have cancelled the "PLAN" 2 years ago and she put me on hold and after a few seconds she dropped the phone in my ear. Debit order was supposed to be for "DEATH PROTECTION PLAN" However - I Went to FNB branch in Denlyn 2 years ago to cancel the ''DEATH PROTECTION PLAN" Why is FNB still debiting my account every month after cancellation??? The Consultant informed me that FNB will refund me all the money that they have been debiting after cancellation - When will the money be available to me?
