I also kena this recently. In my case it was USD17 for Strawberrynet.com and USD125 for "Facebook Payment Interna" both on 30/9 within a minute of each other.

I called CS, card will be cancelled and replaced at no charge, but I have to fill in a dispute form to avoid paying the fraud amount. Is this the same process CS advised you?

Edit : If it matters, this happened on my AMEX and I called the overseas CS as I was not in-country and could not call the 1800 numbers.

They told me to wait for next month statement (and they assured me that it wouldn't be credited). They said I can only file the dispute form if the amount is credited in the statement.    Will update again if there further development.

If I am in Thailand, I will have to call Malaysia's MBB to activate my credit card overseas right?

either that or you can dispute it once it shows up in M2U

Great!    Thanks for the valuable info. Now i can utilise more of MBB2's rebates coz my Titanium sure full every month.

is there any default sms alert value for mb2cards?

They sent me alert for purchasing apps costing USD$0.25.  Maybe local currency have some kind of limit?

I still haven't see my rebate for this month, anyone the same?

Limit can be set by email to Maybank CS (refer 1st post)

I still haven't see my rebate for this month, anyone the same?

I swiped my card on midnight 30th September (12.30 a.m.) and posting date is only on 1st... There goes my hope to include it in my September rebate.

The rebate should follow the transaction date right?

Can share which merchant which is 1-day late ?

my one particular transaction on 29th sept is still not in statement...even after i got the rebate statement (rebate not including this transaction) 

If it doesn't get posted is better than getting 5% rebate, right ?

You no need to "activate" for overseas usage but it is a good practice to inform your card issuer the period you are overseas so that they do not block your card in the event they cannot verify  with you your transaction.
