DCB LTF under alumni offer

[alt578]

I recently opened an HDFC salary account (via branch) and have 2 salary credits yet, and I don't have any credit card from HDFC yet. I want to apply for DCB LTF under the alumni offer. What is the best way to apply for it?
I started getting preapproved card mails from hdfc and while checking for eligibility, my preapproved card is moneyback with 35k limit😂.
What is the CL I can expect from DCB if I get one?

Alumni offer ended by Oct-2023. It will be spend based LTF for now or long term association HDFC with higher spend patterns.

LTF spend based offer is still fine with me if it's just 1 time spend, do you know any agent who can help in this?
