Why have a procedure if your support doesn't follow it? Even if you have a procedure, everything falls apart when it isn't followed. This is the same as having no procedure at all.
People make mistakes. The customer support person was probably just trying to be helpful and not fully aware of all the ramifications. This is unfortunate but presumably there has been some retraining.
