It can be said that 600 tasks per month are basically impossible to complete. Of course, it depends on your social connections. If you use up all the people around you, your work is almost over, but if you have no performance or poor performance, the bank will not take the initiative to dismiss you. Resign if you can't make money. I worked in a credit card center. It can be said that there are resignations and new employees every day. This job won't last long. Think for yourself.
