Axis Bank has done an unauthorised debit transaction vide ECS of Rs 50,000 from my mom's savings bank account. My mother has never signed any ECS form for the same. Still Axis Bank guys have debited the amount. I feel it is acase of forged signature of my mother. I want to take proper steps against such offence which is considered criminal offence in our country. Kindly guide me on how to take steps against such actions ?

Thanking You
Mrs. Debolina Choudhury.
