So I also tried to close and get LTF but Yes Bank closed the Card straight away and no retention calls . Even though I had 3000+ excess credit and more than 17000 rewards points . When contacted customer support they bluntly said they don't contact if any request place through app.
Not worried...
IDFC first is giving Credit card limit enhancement. Whatapp massage received for the same in one card but not received for another.
But sent "LIMIT INCREASE" on other card also and received confirmation.
Everyone can check
