Surprisingly existing card holder is eligible for another gift criteria, and also the guaranteed gift.

I have M2P, then recently I applied for Islamic amex platinum, they gave me a separate credit limit, I thought that was normal? apparently not?
Seems I was 3 weeks too early to apply for it, otherwise I would have a shot for the gift, there's no more card that I want from maybank now.

I'm not sure why some comments mention you can't get islamic credit if u have maybank.

Just to share my own experience, I have maybank cc, I applied online for islamic card on December '23, and "instantly" got approved.
Why is say instantly is because, after I submitted, I check on MAE and saw the card, realised it's the wrong card showing, I immediately called to cancel.
I was told there was no system error, so they say likely it's human error on my end. The card was immediately cancelled, as shown in MAE app. 2 days later, the card arrived at my house.

On Feb '24, I apply online again for the card that I wanted, wasn't because of cooldown period or anything, just that I was lazy, and didn't really need the card.
Got "rejected" this time.

Then I went to Maybank credit card center and told the staff what happened, the whole story above, and he say can apply again with him. Approved this time.

tl;dr Probably you can try to apply at Maybank credit card center if you really want the card, and not the ringgitplus gift.

No, I think calling won't work, probably you can visit your nearest maybank branch, they can help to submit as well.
