Customer Support: Hello, this is Standard & Chartered. This is Ana speaking. May I help you?
Caller: Hello, Yes. I like to complain that I don't have any credit card with you, but yet you are billing me.
CS: Before we proceed, I need to verify you. Do you have a supplementary card, Mr. So and So?
Caller: Hellooo. I just said I don't have a credit card how can I have a supplementary!!!!
CS: This is Bank Negara's ruling, we need to verify you.

CS: Can you just answer, yes or no?
Caller: No.....
