HDFC Bank — Continued harassment for payment

1. Personal Loan EMI bounced on this 4-Sep-15 due to job change. 2. We promised HDFC bank that we will repay by this 30-Sep-15. 3. They still call us and our relatives multiple times in a day for repayment else they will put our case in recovery department. 4. We are arranged for a EMI in a form of cheque which we will deposit in our account on 28-Sep-15, and it will get cleared by Wednesday (30-Sep-15). 5. We are ready to give post dated cheque (dated 30-Sep-15) to HDFC bank, but they are refusing the cheque and will only accept cash, which we are only expecting by 30-Sep-15. 6. I am not sure if they do not have a policy to grant at least a month for repayment of a EMI.
