Nedbank is sharing information that is misleading

I tried reversing a debit order on the 30th of October, and I was told to wait for 2 business days. The money is still not in my account but a reversal fee has been deducted. I reached out to the Nedbank customer service they said I can only reverse a debit order within 30 days but when I check their website it says 30 days. And they still deducted the reversal fee though the reversal request was not done
