cant really think of any which tied to the bank...but if they 'only' see how much money i have in my main account and then make the judgement..then  ....i do put money on other investment..saham etc

yet few months ago..maybank did called up to offer me credit cards which i turn them down...now when i approach them for the credit card..they rejected my application
