Confused

On Thursday 5th April, I went to Palm Springs Mall Capitec Bank to ask them to suspend a Debit Order from Debiting on my account.

Then Teller who was assisting me assisted me on that machine and he said that the debit order is suspended. I even checked on the App, it showed that the debit order has been suspended,

but to my surprise, the company that has been suspended to debit on my account, managed to debit on my account on 6th April after it has been suspended.

I no longer want these people to debit on my account, hence I asked Capitec to suspend the debit order. So I would like to know how is that possible? So can they still debit after they have been suspended not to debit.
