i've been using the ikhwan mastercard for some times now, but never activate the petronas card since i did not pump petronas. does anyone know its that mean that the petronas card will lapse automatically or i still need to call to the CS to ask for cancellation of the Petronas card?

besides, can my ikhwan card still be use if i cancel the petronas card?

i dont really calculate what is the actual CB every month as long as it is credited to my account. however, when i tried calculation how does the CB works, i always found the CB amount is not tally with the actual amount i spend. any sifu can help?

dunno how to post the snapshot here, so here are the transaction details:-

posting date transaction date transaction description amount
4/3 3/3 shell 68.70
6/3 4/3 tesco extra 20.10
6/3 4/3 tesco extra 120.15
17/3 17/3 aeon 29.75
18/3 17/3 aeon big 15.20
18/3 17/3 jaya grocer 31.50
1/4 31/3 cash rebate 14.24

all these transaction are perform on friday or saturday as the date eligible for CB.

Oh my u are right. never knew it was calculate per individual transaction.
thanks. any idea does this calculation applied to all Maybank credit card?
