I'm black speaking chinese and it works ! Marvellous

got the cll today but did not answer...made it a habit of not anwsering numbers i don't recognize...also have to turn the ringer off...if it's important they'll leave a message.

Also got this phone number as an incoming business call, but didn't answered too. Simply because I recently received another call from 4029303659 (also an unwanted call, check this out), from which I confirmed my business infos without knowing why... Now I can make a direct link between this and all that "spam" I recently received on the line... Since then, especially when an unknown area code ID is displayed, I simply refuse to answer.

they don't give up !

I just got a call from this same number and they left a message. The message said it Lisa from my Credit Card Company and that I could reduce my interest rate to 6%. To me is sound like a telemarketer

Never picked up, but according the above posters it must be spam/scam/fraud.
