so many cc for your gfs expenses. 
later add another new gf from ocbc whom you interested with. 

Called to cancel my card on Tuesday morning. Until today, no call from the card retention department. I bet they're willingly to lose existing customer base and fishing whole new basket of customer. Therefore, hoping for annual GST waiver is very thin.

2nd year annual fee waiver, must call in to call to waive.

if can use back same number but the card is upgraded, then all the autobilling no need change 
look like have to maintain this card in order not to trobulesome

WMC no annual fee for the first year, cashback 1.2% unlimited. Annual fee - Principal card: RM388 per annum, Supplementary card: RM188 per annum. So cancel before the first year is up?

not too long ago just annually RM60k requirement.
i think just up to RM100k.

do you have OCBC Titanium? Last Dec/Jan i got upgrade to MC World.
But i don't see much benefits to this card at all but worse have to pay AF RM388.
