hello guys, so I am 21 rn. When I was 19 I had onecard fd based (22k limit), paisabazaar step up card (15k limit), then after using them for one year i closed them. Then I got paytm postpaid offer so I used it but closed after few months because of the charges but I had 10 rupees pending which was not showing while closing and my postpaid was still active but my access to it was closed. Like my paytm account was deleted but postpaid was active and after a few months got a call from aditya finance and tehy ased me to pay 50 rupees after which they closed my paytm postpaid account and give me noc too. But it got as default payment due to which my cibil went down. So pls suggest me how can I improve my cibil score and get credit card. Currently I am holding kotak fd card with 25k limit and how can I get it unsecured and upgraded. Also I have savings account in hdfc and sbi too. I want a premium credit card. Sbi is offering me sbi prime against fd of 1 lakh and hdfc is giving freedom which is a basic card. Which premium card can I get for a fd of 1 lakh.
