Address:

Mumbai

I filled a form for po post in nanital bank ltd on 15 september 2020. When first time i did the payment, rs 2030.68 got deducted from my account but it was not reflected in the application form. So i have to done payment for second time in which it showed payment successful.
So i want refund for the redundant payment deducted from my account.
