Nedbank card delivery charge without my consent!!

I have opened a Nedbank savings account recently, in order to transact between my various accounts. I was contacted by an agent in connection with a card for the account. Delivery of the card was offered to my home at no cost. However, when a deposit was made into the account, a delivery fee of R160 was levied!!

I contacted their contact centre to complain about the charge, and to request that it be reversed. The agent insisted that the delivery to my home was correctly billed and nothing could be done to reverse it.

I would like to ask Nedbank why delivery to my home was offered at no cost, when it should have been explained that there was a charge of R160? Do their agents not know what the delivery cost is? I'm certain that they can review a recording of the conversation where free delivery was offered. In that case it should be possible to reverse the charge? I'm extremely unhappy with this level of service, if I had known there was a change for the delivery I would not have accepted the card.
