Scam or fraud: Hdfc Bank — negative balance in my hdfc account

Hello Sir/Mam, this is Shraddha.I hereby want to tell you that in 2016, I joined a company to work with, in Indore(M.P.).They applied for my HDFC account and paid me through that account.After a few months I left my job and also didn’t maintain or focus to maintain amount in HDFC account and finally when a few months back I bought some item from Flipkart and when I didn’t like it, I applied for return the product and used HDFC account details to refund my money.When I didn’t receive any credits in my account I checked my statement of HDFC bank by dialling the no. [protected] from my RMN, and I was astonished when I saw the mini statement, it was more than -7000.There is no rule for customer to pay this unnecessary amount so I appeal you to waive off my negative balance from my account and close it.
