1. Can anyone tell how to apply them on Card-to-Card basis online? I have a Tata Neu Infinity HDFC credit card whose credit limit is around ₹1,80,000. But it was approved just 2 months ago. And my Amazon Pay ICICI CC was approved 3 months ago, with a closer limit. I don't have any other credit card.
2. Is it even worth getting their entry-level LTF cards? I mean, do they bother you with spam calls and messages even after you get rejected?
