I will try to keep it as short as possible, so basically I was looking to open an account in a private bank around new year time, and decided to go with HDFC Bank, a good friend of mine suggested to rather go for HDFC SavingsMax variant and I did, kept 25-28K in it all the time
CC offers started popping out after 3-4 months or so, it was MB+, paid, got LTF for the same, upto 40K limit it said, later limit was up to 1L, but my eyes were on Millennia only, and that too LTF
Kept on waiting and as the time passed, they switched between Freedom, MoneyBack+, IOCL cards, but weren't interested... I had very less hope for me to get Millennia as LTF, thought of trying C2C method
But got lazy and didn't do it, apparently they did give me an offer for Millennia CC, but 1K was the fees, waited for 5-10 days more, and voila, started getting LTF notifications again, applied and got the same!
