[Resolved]  HDFC Bank Bank Credit Card — card is closed around 3 years back

Dear Sir,

Please be informed that HDFC bank is one of the most fraudulent banks ever realised.I had a HDFC bank credit card around 4 to 5 years back.And teh card was settled around 3 years back because one of the collection agents abused my then boss.Full and final settlement was made and the issue was resolved.
Today after 2 and half years they come back saying an amount is overdue.
with a bank notice.
Please advice.
As i am married now and my parents live alone.

Regards,
Ani
