Consultant told me to pick another bank

I went to inquire if I can stop a debt order cause I just settled an account in advance in the store upstairs, I showed them receipts and all. They told me that they can only reverse a debt order when it has gone off which is fine as the contract was not with them. Before I have requested debt orders to be stopped with Standard bank it was not a problem. I understand new rules have come not a problem but for the consultant to tell me well try another bank if you want that facility was absolutely not on.The fact that she said this is not FNB in rude manner .I even said to the consultant sorry are you been smart with me, cause that is not how you should talk to your customers. I couldn't believe what she was saying to me.
