i'm not with any banks, so the below answer could be incorrect...
First, you need to understand how the interest is calculated.
Secondly, you need to check whether there is any penalty on early settlement on the 'balance conversion'. There is usually a 'product disclosure sheet' explaining all the terms and conditions of the 'balance conversion' and how the fees and charges are calculated.
As for credit card balance, my monthly statement has all the details on charges and fees listed on the reverse side of it; which I believed is standard for all banks in Malaysia.
The interest is calculated on daily rest basis; ie. number of days the amount is outstanding / number of days in a year X the interest rate.
Since each line of transaction is calculated separately, am not really sure how the payment will be apportioned to each debt. Most likely, a fix (monthly) amount will be deducted first for the 'balance conversion', and the balance of the payment goes to the credit card debt.
In view of the interest calculation on a daily rest basis, it would be better to pay more each month than putting the extra money aside for a full final payment.
You could make it simpler like holding onto the RM1k first and pay it together with your usual payment the following month (before the 5th.)
Cheers.
PS. I paid my credit card the full amount every month. On the reverse side of my statement, it is stated "The interest free period of 20 days is only for retail transactions and only granted if you have paid the previous month's outstanding amount in full". In other words, a credit card to me is 'free' credit/money to use first, not an auto personal loan...
Incidentally, someone from the bank called me last week, to offer me a special low rate on cash withdrawal... no paperwork, no document, no need signature... just say yes over the phone, and she will deposit 12k into my current account. It will be debited monthly into my card over 24 months... less than rm600/mth...

Thanks for the reply.. Will look into terms and condition.. Can't wait to live debt free..
