Dear sir,

Which should be reflected in my account by 31/01/2018.
Manier times i called customer service care[protected] of punjab national bank and also visited pnb branch (Moti nagar, delhi) with refund reference no: 75503728022017680793294 of the refund: rs.1000.00 but they denied to take complain and process of charge dispute file.
