Indian Overseas Bank — Poor Customer service

Address:

Chennai, Tamil Nadu

Indian Overseas bank provides a poor customer service,
i reside in Velachery which is in the southern part of chennai whereas my salary account was created in the kilpauk Branch which is northern chennai.
Recently I withdrew a some of 1000 bucks from an ATM machine which belongs to some other bank and a cash was not dispensed instead the amount was debited from my account,I called upon the bank customer service and the redirected me to the nearest IOB branch next to my home, I spoke with the officer in the IOB bank near my home in regards to this complaint and the officer said he cannot take a complaint there (despite of all banks being centralized) me to write a letter in writing (there is no complaints - Email Id for the bank),

I asked the officer politely if i have to take this issue to the kilpauk branch during the normal working hours then I have to take a half a day off or at-least an hour's permission from my work. the officer near my home branch was least bothered about my requests and shouted on a loud tone, "i[censored] want your money then take leave else get out now" Is that a way a bank works ? IS that how a bank treats their customers ? would someone be ready to have an account in such a bank who provides a poor customer service.

Adding more pain to that when i went in person and contacted the officer in the branch in Kilpauk, they were closed down for lunch, I was standing in a brach which has no chairs for the customers for 1 hr and finally the job was done after much hesitations from the officer as if i was asking money from their pocket.
