HDFC Bank — Credit card outstanding

I have hdfc credit card holder I have using past 2 yearyears. I have using the credit card properly on every year, I could not pay the full amount within the credit period before due date. Hence, I have paying only the minimum due every month. So, my outstanding balance increased due to the interest which I could not afford and pay. Hence, we decided to close the credit card and we were planning to convert as emi.

I tried to contact the person regarding the issue. I have contacting customer service continuously. But they told many time, offer is not available in your card and offer will be provide later untill wait. I need my outstanding balance amount to convert the emi option which is possible amount of my outstanding amount. Please consider to my obligation as early.
due to covid 19 i want pay my whole outstanding amount but pay in emi not able topay full amount..plz convert my outstanding into emi
