They very "Fan" one la. I work shift, need to slp during afternoon. If forget to put phone in silent, sure tio auto alarm from them. Furthermore, my spare line, I NEVER give out, still got unknown call from them. I now have the habit of not answering unknown call but also quite bad cause those who knows me, call from another number, also kenna rejected. What if they really need my help? That's why I say if I can beat them up, because they making my life miserable. Got once, I actually walking near the MRT track, got a call. Then he heard MRT sound, he thought I inside the train and stop the conversation. I know they want to earn a living but what are their chance of success for finding a customer? I think they should be ban, as they are consider hidden "ah long"!
