HDFC Bank — Negative balance

Address:

Hyderabad, Andhra Pradesh

My salary account(in HDFC bank) 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) in the month of march 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(lost in 2 years back and i never requested for a new one). I logged into my account for some reason on 1st September 2014 and i see that i have Rs 3900 in my account. I request you to please take action against this bank..Thay have no right what so ever to do whatever they want without informing the custome
