[Resolved]  Shaha Finlease — Standard and chartered credit card harassment

Dear Sir,
I had credit card issued by Standard and Chartered Bank in 1999 and i closed this card by payment of Rs 10 thousand including all fines and overdue payment in the year 2000 as one time settlement. The bank issued me letter also of No dues.
In 2017 Shah Finlease person called me and said and said your credit card overdue amount of Standard and Chartered still outstanding and we bought Standard and Chartered credit recovery and you have to pay or we will go to court.
Since I already paid the dues, I refused to pay. Then till today's date of 27/01/2022 not heard from them.
Again on 27/01/2022 they are calling and sending mail to pay.
I don't understand what Standard and Chartered bank was doing from the year 2000 if any outstanding of card was there of any customer. Am I supposed to maintain any documentary evidence for 17 years in possession of any banking transaction which was closed for such long period. I need answer for this from Shah Finlease on this.
