Wrong information by employee

I went to African Bank branch in Boulders on the 14th to pay my account that was in errors and asked for my card to be replaced and the consultant did agree that after paying i will get my card replaced a day after i called African bank consultant they said i was given wrong information at the midrand branch so the 17th i went back to the branch n told by the manager that i cant get a refund due to my status on my account even if their employee has given me wrong information wasn't happy by how the situation was handled
