Finally got my CLI after having my It card for 4 years now. I've had my initial CL at $18,000. They had given me $300 within those 4 years and they've always denied any increase I tried to do on the website.
But today, I submitted a request and they gave me a CLI of $2000! Finally, my first $20k+ card! Yes!
That makes over $80k of credit available to me for that I'll never use!
