IBG pay for normal aeon CC only 10 sen. But it does not work for watami.

rm1 charges is for 'bill payment' to AEON Credit Service via m2u, while cimb only charges 60 sen.

Wise move!
I have been paying insurances using this card since it was launched. Attaining 3K for insurance is not very difficult.

I don't use the Watami CC for the merchants you mentioned. I use it for transactions that would otherwise earn less than 3% if use other CC, eg Insurance, bookstore, car purchase deposit and many other merchants, in fact I use it more often than my other CC. This is my priority of using CC HLB-Wise>MBB2Amex>Watami and other CC during special promo eg. SC-parkson-voucher, CIMB-CashBack, Citi-Cashback.

I was thinking of applying for new aeon credit card for free balance transfer. However, the requirement to pay additional rm1 for every payment made makes it less attractive. I may end up paying 0.6% for every rm1000 spent, equivalent to 7.2% p.a. Unless I can make more than 7.2%, else it won't be worthwhile, correct?

You are absolutely wrong... or rather mislead by AEON's incompetent CS.
I've been converting 12500 points into RM50 credit into my CC each time I get >12500 points collected.

Received SMS to remind me to pay my statement balance about 1 week before the due date. Good practice from Aeon.

You are good to received voucher, I don't have it... 

Btw, seem like Aeon take quite some time to process credit card application.

18/2 - Applies for Watami card
26/2 - only received a call from CS for verify (after complaint to SA)
3/3 - Called to check the status, under processing 

Probably the card will not be ready on this week IF the application is successful.

still holding my payment, waiting for Watami card to be arrive... 

Submitted to the salesperson at the booth in Aeon Big, Prai.

I checked the status by using the Aeon's Interactive Phone System. From there I got to know that my card has been approved. Just wonder if it would take how many days for the delivery.

same here, not in my March (3rd month Statement).

Must check and make sure its in April (4th Month, RM150 CB, else will write to AEON to complaint and if no action, follow-up letter to BNM

Wow not GST, how about annual fee, waive as well?
Your spend a lot with your aeon card?... 

This is news... Have you receive the "refund amount" after a few days ?
Can you post a screenshot on how you fill the IBG form on SCB Online Banking portal ?
