AGAIN, no service

I called 082135, we need to change bank details. The debit order need to be changed from my husbands bank to my sons bank. First they told me no it can't be done, so I asked to speak to someone at account. They put me through and after 42 min of holding on a lady answered and said we must go to our nearest branch to do that. So we drove 40 km to go with my son to Vodacom. We printed everything we needed and when we got to the shop, they told us they can't do it, accounts department has to do it. So accounts department now you going to call us and sort this out. My husbands account has been closed, so no payment for you unless you call me.
