bro got Tao Tai Chee! let Datuk analyse for you.....after reading all the bros comments I can say this is the work of a boliao 'friend' close to you. There is also high chance he is not a Malaysian but a anyone with a prepaid card. Most Malaysian phone switch to home network in places like Woodlands/Tuas/Kranji so this person might not even be physically in Malaysia. This is nothing but a prank to unsettle you.....go back and think which friends of yours is doing this. Another probable but highly unlikely scenerio is that someone is using your namecard going around impersonating you and pissing people off! Anyways if really your VCD come out i will go buy a copy
