The only reason I am having this card because its free... I threatened to close, every time they put an annual fee.. and finally told them, if they ever charged me annual fee again...I wont even consider retaining it.. and since then (must be 3-4 years) there have been no charges.
I doubt I will be able to make 60k worth of payments in card bills annually. EB, BSNL bills might help as they would be more than 5k per month average across the year, but I also think they put a service charge which moots the whole point of using this card..
