[Resolved]  PNB Bank / ATM Cord — Amount withdraw from block ATM No: [protected]

Sir, I am Ajay Kushwaha, holding an account in PNB Bank, Branch Siwah, Panipat, Haryana with account No: 313800 [protected]. I had opened my account in PNB on 11 Nov, 2007 and ATM card ( No:[protected] was issued to me on the same day. On 5th March 2008, I informed bank to block my ATM No as I came to know that an unknown person had withdrawn amount Rs 10,314 ( in two shift of amount Rs. 5017) from my account on 23rd Feb 2009 using my ATM Card. The Bank had issued new ATM Card (No: [protected]) on 16 June 2008 and told me that my earlier ATM No had been blocked by them.
On 15th Sept 2009, I was shocked when my cheque got bounced. On investigation I came to know that an unknown person had withdrawn total amount Rs.12000 in two shift on 13th Sept 2009 at 11:33am (information given by customer care on telephonic conversation) from my OLD ATM NUMBER but as per my knowledge that number was blocked by bank as this was told to me at the time of issuing of new ATM CARD.
I discussed this matter with the branch manager (PNB Bank, Branch: Siwah, Panipat). He replied that he could not do anything and he did not have any record of my Account so the only solution is to open a new account and close the present account.
Kindly take necessary action to help me in this regard to get my money back as this is due to carelessness of bank. Tell me what to do? I am very much disappointed since this is not a small amount for me and covers a big part of my salary.

Waiting for reply on urgent basis.
Ajay Kushwaha
