Jan Dhan Account

Hello Srikanth, This is Parveen, what i want  to know is my husband has a Pradhan mantri Jan dhan a/c. which is as per my knowledge a zero balance a/c. But the bank people are deducting money from his a/c. for maintainennce of minimum balance every month,secondly if he uses other bank to draw money once in a month their also they are deducting money Rs. 22.25 per single transaction although we have 3 swipes optiona from other bank's per month. Thirdly in the month of May 2016, he was eligible for a overdraft from the a/c., but the Andhra Bank where he has a/c. is telling him to contact head office, go there, here and not responding nor providing the ODF.They are also informing him to maintain a minimum balance in the a/c. Simply they are cheating and deducting money unnecessarily. Please tell me how to solve this problems? Regards, Parveen
