[Resolved]  Kotak Mahindra Bank — Settlement of credit Card kotak bank

My card number was [protected]. In year 2019 I have done settlement with kotak bank and done the payment . They had given me the settlement letter only on whatsapp. I have all the proof of payment but still m receiving the legal notices and abusing calls from kotak bank. Since m heart patient requesting kotak bank to pls check my account from year 2019 to know the details. They are forcing me to pay 65000 immediately. I am writing this content continuously to kotak bank also but they are not replying it
