what he meant is ur hlb and rhb doesn't have the same card number 

Please explain which NRD you go where your IC got 16 digits and not 12 digits?

Also - bad news - almost all Malaysian ICs already leak with associated personal details (generally phone number/email address) due to numerous data leak/stolen over the past decade. Your winner announcements aren't a good source for that.

good example is LLK https://forum.lowyat.net/topic/5066366

multiple winnings from different banks/promos, all share different masking. combine all together, can get his nric and mobile number

a lot of citibank users gotten conversion timeline email last week already
