Debicheck mandate removal from my banking App because the policy is nolonger active

I have recently cancelled my funeral policy with clientele I even got the Email confirmation I did send emails requesting them to remove their Debicheck mandate system on my banking App still to changes instead they are busy trying to bypass my bank restrictions using EFT methods to deduct money from my account for a policy that's is nolonger active.

please clientele stop trying to ***** my money because I have proof that the policy has been cancelled what you guys are doing is *******.You were supposed to remove that Debicheck mandate from your side in the first place..Remove it with immediate effect
