HDFC credit card. Review on HDFC Bank Visa Credit Card

HDFC CREDIT CARD . few years back I applied for HDFC credit card as I was already having MAX saving ac with HDFC .With in a week I got my card. But I didnt used the card for around an year but on diwali I bought a led on HDFC EMI scheme. They converted my amount into 6 emis. My bill used to generate on 13th of every month. After depositing 6 emis hdfc stopped mailing me the statements on 13th and I thought its obvious because I have paid all emis and there are no dues. But after 8 months one day I got a call from hdfc that I have a payment of 6800 due because one of my payment was deposited late by their executive. I had lost the receipt of the payment and they started callingme every now n then for the payment. I tried my level best to convience them but they didnt wanted to hear anything.finally I had to make the payment to them .HDFC is a fraud bank.
