i called ealier this week to cancel the plat wise CC and a lady called me back.
if i understand correctly, the bank offered to cancel the plat cc, and re-issue a gold wise cc, which comes with 1 year free AF and one time RM50 reimburse for GST.
it's a good deal for those who able to maximun the cash rebate each mth.

unfortuately i was rushing at that time, and the officer wasn't too clear and sounded a bit unsure, so i declided the offer.
