ICICI Bank keeps rejecting my credit card — any suggestions?

Hey everyone, I’m 24 and self-employed, don’t have any formal income documents. Currently holding:

SBI Credit Card – ₹1.05L limit

Axis Bank – ₹1.48L limit

HDFC Bank – ₹1.34L limit

PNB (FD-backed) – ₹48K limit

But every time I apply for an ICICI Bank credit card, it gets rejected. Tried twice for Amazon Pay ICICI and once for a core ICICI card — this time it was rejected even without a CIBIL inquiry.

Any idea how I can get an ICICI card without income proof? Would appreciate any suggestions or alternative routes. Thanks in advance!
