My father Late Mr. Ram Pyare Yadav was working in Bihar Government in Jogapatti Block distt- Bettiah, Bihar as a Senior Clerk. He had a salary Account in SBI ADB BETTIAH branch DIST PASCHIMI CHAMPARAN, BIHAR 845438. In 2011 1st July he is passed away. At that time his account was having 1.64 lacks rupees. In the same month we have given notice to the branch about the death of my father. Actually at the time of account opening he missed to put the nominee name. We are three brothers & one sister given NOC & appointed our mother as a Nominee for that Account. And also given all authority on paper her to receive the money. Even then we talked to the SBI branch Layer regarding this & as he told we have completed all the document formalities. In spite of this we have not received our money. After that many times we have met & talked to the Branch manager but he is not responding properly. Kindly advise me what to do. We are planning to go to court regarding this if we will not get money in this month.I have also mailed this above mail to email@example.com & firstname.lastname@example.org two times but I didn't get any answer.
