HDFC Bank — ppf account

I had requested and filled a form of opening a ppf account in azad nagar, andheri west branch. I had paid the amount by cheque and this was done in march 2017, an employee named manali took care of it. Today after 5 months, when i visited the same branch to deposit 30, 000 in my ppf account, i get a response stating that the ppf is not even opened. I think its bank's responsibility to at least inform me if there was any pending signature, this was stuck for 5 months and that too i came to know when i visited the branch. And fyi, the same employee manali has not yet given any update, whenever i call her she ask me to call back later. The office boy helped me in finding the status of ppf account by coordinating with front desk. Can manali be little more responsible about customer's money, from and reliability

I request you to escalate this matter asap
