HSBC Classic Credit Card
Card Cancelled by HSBC without any Information

Hi

I have HSBC Classic card, I have used my credit card once to Purchace the Jwellary and latter on i have converted my bill amount in to the EMI. After one month HSBC says that they have cancelled my Credit Card without informing me. And now they told me to pay the all amount. What should i do in this case i am ready to pay the same EMI.
