[Resolved]  HDFC Bank Securities — Refund of Rs. 1976.41 debited from my account without any writen confirmation

Dear Sir, I have newly opened Dmat account with HDFC Sec as per terms they debit Rs. 999/- as openint charges of Dmat a/c. But further HDFC Sec debit Rs. 1976.41 from my account without any written confirmation and when I call to customer care they ask we will provide the service and you confirmed the same over phone and we can listen your voice recording. But I continuously saying that I don't want any special service even I have send email that please I don't need any special service. They ask me that it is non-refundable. They don't give any written reply of my email. Now I have repeatedly request to refund of Rs, 1976.41 and close my demat account but they are not responding of my email. Please arrange to resolve the issue for refund of money. Regards, Santiswarup Chakraborty
