drop a mail and they wont change the GIC ..GIC doesnt have the name of college on it ..u can change and u wont be issued new GIC ..they are not mad peeople ..they wont isue the same thing again when there is no change required on the GIC itself ..just a drop a mail to them indicating ur particuar like ur name passport number and DOB and account number and tell them that the new call letter is this please update (i am telling u to do this cause the CHC has the right to call SCOTIA bank and know ur details ),...the updation is just for their refernce nothing else(no changes would take place )..its like telling them ki haan bhai college change kar lia FULL STOP ..no complications !
