Extremely pathetic service

I have received a sms yesterday evening saying that I have not rep**** to standard banks correspondence and that my account may be handed over. So I called the next morning to find out what has happened as I did not receive any correspondence from standard bank. They then informed me that my account was handed over. I then asked them how can you hand me over when not informing me how, or why, or even giving me a chance to correct any error. How can standard bank send a sms late in the afternoon to call them back and the next morning when you do your account is already handed over. The issue was that interest of the account was going of the wrong account and they called me months ago to tell me that the payment did not go off. So I informed them of my new account and said that they should make all interest payments from this account. I don't know what the issue is as they did not call me to inform me that any additional payments should be made. I did not have a problem making any additional interest payments, standard bank just neglected to inform me that additional payments should be made and neglected to debit my bank account.
