HDFC Bank — About Closing Account

Address:

Pune ,chikhali

Hi,
My name is Priti Pawar. I joined a company in the year 2018 and that company opened my salary account in HDFC bank but didn't gave any basic terms and conditions of salary account. I left that job after few month because of study reason. At that time my account balance was less than Rs.10, 000. Now my salary account in hdfc bank has been converted to savings account Without informing me.
Now it showing negative balance of -6678.I am totally shocked and worrying about the same.I don't want to pay any penalty, I want to close my account as soon as possible.According to new RBI guidelines banks are not supposed to penalise for dormant accounts but when I contacted the customer care they are refraining from closing it saying I have to Pay the fine.

Bank:HDFC, Chikhali, Pune Branch
