Fnb allowing double debit even after rejecting mandate.

I have declined debit order mandates. On my app it shows as rejected yet you as FNB allow double debit orders to go off.

I want my money reversed as I have already made payment via EFT.

I am not supposed to have any debit order on my account as I have not accepted any.

I want my money. Can’t believe after rejecting you still debit my account. I want my money. And I want to know how it is possible????? You guys better get back to me.
