I emailed them for upgrade and they refused with the following email:
But the next day I saw the upgrade to Marquee available on the IRIS app and net banking, but it was a paid upgrade with 9999 fees.
But also, as you can see in the screenshot above, they rightly or wrongly wrote that charges will not be applicable:
'Further, in case of any upgrade in future or transfer to another variant of card, the fees and charges specific to variant will
not be applicable.'
So I sent them another email saying that I am already eligible for paid upgrade and demanded LTF while citing this line from their reply.
However, unfortunately they still declined:
Is there anything I can still do to get the LTF upgrade?
