Violation of the privacy act

I keep getting this a clients banking information and notifications. After having been called on Saturday 03/11/2022 the consumer service agent promised me she would update me on Monday weather or not the issue will be resolved but nothing happened. After they promised that i would get a reference number and that they would contact the client to change his information. I am still receiving notifications from the clients bank account Do these people not understand the risk they are exposing this client to. It is your job as a bank to protect your clients personal and financial information. Someone could use it maliciously.
