woolworths refusal to upload banking details

I am no longer banking with my current bank. I am a private wealth client at Standard Bank. I called woolworths trying to change my banking details. I was told that the banking details cannot be changed because my bank is few days old. Would I even go through the effort of notifying Woolies regarding my new banking details if I had intentions to **** them. I mean, it is a private wealth account. I am a Dr. I don't have time to be going to the store and paying accounts. The theory of a bank account that is new does not work. Please sort this out, otherwise you will need to handover the account because it won't be paid. Unfortunately, I am too busy to being driving to the stores and paying bills.
