tips if receiving call from promoter (usually insurance):
just tell the promoter u didnt have any credit card.
usually they will ask - how about maybank visa debit?
just reply - i'm using visa atm card, dont have visa logo.
if cs said - but here got record u have credit card?
reply - i already terminated it. maybe bank didnt update yet. if u dont believe, call bank and ask them.
<end call>
(usually they wont ask the bank, coz bank wont entertain them. they may call u back later 'konon' already verified with the bank).
what to do? after end call, immediately save the number under <whatever name that u dont want to answer> then set 'blank/empty' ringtone for that name

sometimes, promoter will politely ask do u have time now?
reply got work, pls call me back next 40 mins / 2 hours <u set the time>
after end call, do the steps what to do above
