HDFC Bank — Hdfc credit card payment related

I made a query to hdfc bank regarding my paymnet of credit card. Since i was not able to pay dueamount of hdfc credit card and also did not want my credit score to be affected as well interest and fine charged on non payment i wrote a email to hdfc requesting of some method so that i can pay the due amount in parts or else i can can be given some kind of payment holiday. I wrote the email 17 days back in advance and kept on sending reminders also but no one replied. I also escalated and worte email to higher ups but they also did not replied. They totally ignored my issue.
