Indian Overseas Bank — no online number update!! poor net banking service

Address:

600053

I need to update the bank account register number to new number. I tried updating through online portal but i found no such options.

When checked through customer care service, i came to know that only way to update the number is to go to bank directly and request via letter.

I am staying too far away from the bank, infact i am in another state. I really find it is very difficult to travel to bank for this small change where technologies have been developed vast.

It seems to be very poor online service and not upto standards!!
