I am one of those unlucky people who haven't received any upgrade to an LTF CC too. Both in the imobile android app and in the netbanking it shows paid upgrade options: Sapphiro (MC+Am in the app, Visa in the NB), MMT, Manchester.
Current cards: Apay (2.3L), Coral Visa + Rupay (Both LTF) (75K 🥲)
Relationship with ICICI: Mine SB account. >₹200 MAB since the account is opened 4-5, years back.
I feel more bad to see ICICI not offering any LE on my Coral card. 75K was the base limit. It has been 18 months but haven't received any LE offer.
I have stopped using the card since seven months (exactly ₹0 spends) and yet no luck. The Start-and-Stop method is not working for me 🥲.
