How is this even possible? While discrepancies can occur, if I were in your shoes, my first step would be to visit the bank branch and get feedback directly. If you have any specific feedback from the branch manager or any bank official, please share it here.
Secondly, I am trying to understand the scenario where the money went. In my banking experience, this is a very unusual case. I am interested in understanding the details of what happened. You don't need to mention any of your confidential information here, but additional details will help me guide you better.
