Address:	Hoshiarpur, Punjab, 144216
Website:	netbanking.netpnb.com/corp/AuthenticationController?FORMSGROUP_ID__=AuthenticationFG&__START_TRA

I was done transaction of rs. Xxxx through my pnb net banking. But amount was not debited from my account. Than i have done the transaction again. I was not aware that the amount was credited two times in the account in which transaction has done. When i came to know i credit amount in my pnb account back. Pnb charged me rs.11 for this and debit amount from my account.. I was surprised to see the amount in my saving account was in - xxxx rs. It was not my mistake than i don't know why i was charged and apart from that the pnb employees harass me un-necessary. All transaction dates are also different and amount debit from my account without my knowledge or signing authority.
