In SBI Bank we have a locker (Joint,E or S).My father was first holder.But due to his death SBI Locker person says first holder name cannot be changed. They charged Rs.1770 for annual locker rent ( 06.07.2018). So we follow fresh new locker hire process. Charged Rs.3098 (21.11.2018) for same locker. My question is the previous locker rent is adjustable or not?
