one of my friend got airtel card with 15k limit and each month they spent full 15k at that time, they spent whole year 1.8L which is short of fee waiver 2L.
Once fee charged to their account, escalated to multiple people about fee waiver, and explained about usage restrictions, they didn't budge.
Finally card got closed.
3 months after applied same card with different airtel account, got approved with 1.4L limit.
// not suggesting you to try this method anytime, but below 50k not worth for any credit card. and btw, no guarantee in this route - there are chances next card won't approved at all.
