HDFC Bank — negative balance

Address:

500032

My salary account ([protected]) was created in my first company, so once i left the company and joined somewhere else i had to open another salary account. Now my salary account in hdfc bank has been converted to savings account (Without informing me or warning me) i had called customer care and raised a request to close my account as i did not want to use the account and they did say that they will follow up with the request and close the account. After that i never logged in to my account through net banking and i do not have a debit card. I logged into my account for some reason on13 th feb 2019 and i see that i have rs -5073 in my account. I request you to please take action against this and close my account
