becareful Singky banks (unsure about Malaysian banks) has this policy if your account is dormant within a few months (you need to read the application form how many exactly) it will start to charge you banking fees and deduct direct from your account until almost zero then by law it will close the account and surrender it to the govt

sure can but you better check their rules and regulations

i think they pose hefty penalties for dormant accounts and assess by month summore
