This may or may not be a crime, depending on the specific situation. If the amount is not large enough to meet the requirements of criminal offence, it can only be internal treatment or administrative punishment. If the amount of kickback exceeds a criminal offence, it may constitute two kinds of charges: first, the crime of accepting bribes is committed by a state functionary. If it is a non-state employee, it constitutes the crime of accepting bribes by non-state employees. This kind of behavior is the act of asking for bribes in the crime of accepting bribes. As long as there is evidence, you can sue him. Even if it does not constitute a criminal offence, you can report it to the superior of the bank. In short, this kind of behavior will be punished.
If you are satisfied, please adopt it. Thank you.
