Reserve Bank Of India [RBI] — Trouble caused by IndusInd Bank in change of the name.

Address:

Bangalore, Karnataka, 560004

I opened my bank account with IndusInd bank, BASAVANAGUDI BANGALORE in March, 2016. I have a single name and I submitted all the documents required for account opening having SINGLE NAME in it. When they opened my account, the name was manipulated as they added a surname in that which is the initials of my Father's name. It was their stupidity to do so even when i submitted my PAN card, Aadhar Card and the passbook of existing bank account (all supporting my single name).
Even though it was their fault, i followed the suggestion given by one of their representative. I filed a request for name change in June, 2016 and again after that i submitted all the three documents for this new request. After 15 days or so when i received no response from them, i visited their branch again and again however they all are just sleeping. Each time a new demand or excuse. I really have no clue what is so difficult in it for them to correct even after submitting all documents. It caused me so much of physical and mental pain.
