HDFC Bank — Even after settlement done asking further money

Hi team, I have done with my hdfc credit card settlement with the amount of 80k in the given time period of 6 months but at the end paid hdfc team telling that paid 400rs less in the given time, so asking to pay full amount again asking me to pay 70k... due to COVID situaion I lost my job that's why gone for settlement, now again asking to pay 70k for the amount of 400rs.
I request hdfc credit card team to resolve the issue by taking 400rs and support me to overcome in this Pandemic crisis situation.
