I don't think it's possible because both different entity.
Well you can always give it a try.

Luckily i'm enjoying 5% CB through online transaction all the while so this changes won't disrupt my payment method.

Yeah, I will call them when I have made my decision.

I can also get 5% but coming from 10% to 5% does make difference somewhere. Since Sam's no longer accepts ePay bill payments with CC, then I will have to stick to 5% then, better than nothing.

TnG reload, not really an issue for me. Worse comes to worst, TnG Hub is also very near to me, I just reload there with any of my AEON cards and pay with PosOnline. Earn 3% - 3.3% plus it doesn't come with any service charge which is another good thing for not deducting RM 0.53 from my balance.

Your preference is unimportant unless it has basis in actual pro/con. The fact is taking AF into account you get less than 5%. And that having multiple cards can give you more than the total rebate of WISE, without the minimum spending cap. And yes low spenders can spend different amount in different months, which is not possible with WISE.

Here we just want to get the best benefits from our cards. Almost no-one remained loyal to OCBC Titanium card, nor to Maybank2Kard Amex (this one more because at least still has some benefit), nor to AEON Watami. This change with WISE means the benefits are now less than various 5% cards, so why not use those instead?

If you sure meet the 2K minimum with regular spend then keeping this card may make sense (as long as you don't forget AF in your calculation). For those that will be spending more just to hit it, then cut the card. So hard to understand?

Oh, you so you got cash back on 28th Sept ya? Good good. Then, I will terminate.
Doesn't make sense.
I hope you are aware that JomPay doesn't give any cash back.
