IDFC Bank — ATM withdrawal for some people more than one card and for me only allows to withdraw once from any card

Ahmedabad, Gujarat, 380006

ATM withdrawal for some people more than one card and for me only allows to withdraw once from any card, when we stand in line some people who knows the bank manager and the staff of bank can withdraw multiple time and the people who don't know any one from Bank can withdraw only once, which is very unfair, worst experience, bogus bank employees and manager.
I talk with bank manager, she told me you don't have IDFC account so you can withdraw only once and then I told him to do complain against you then she again told me you don't have IDFC account so you can't complain.
So I came here to complain, let's see if anyone can take this complain seriously.
