Wait for sometime, it will be shown as Intermiles amex, phir midnight ke baad normal Amex show hoga. It's just net banking issue of ICICI, they always do this for newly generated cards.
And Congratulations, You made it unlike other guys.
No need to wait for card delivery, just chat with ICICI agent via Imobile app. Tell them last 4 digits of card and they will tell you about ltf status.
