Credit Card Settlement not done

I had a HDFC credit card with 30000 limits. In February '26, I lost my job, since then I couldn't pay the bills, I made the communication with the bank about the same in March '26 over email about the same, they asked me to pay some amount to process the settlement, according to the same communication in May'25 when I got the FNF from my company I had paid 11953.00 RS, I paid the full amount to HDFC, still they didn't settle the account. They kept sending collection agents to my house who harassed my grandparents, my sister, etc. They were very, very rude over calls, threatening with anything they can. I again tried to communicate with the bank over email, but now they are sending me advocate notices. I am jobless requested to settle my account for a very long time; according to the discussion, I even paid the amount I had in my hand, but the bank didn't help at all.
