I tried with my friend number, with public phone, and he didn't pick up at all. I guess i'm just lazy to follow up again, just hope that other would beware of this "ravi6662",.
It's his uncle who dealing with me, and now the person who using "ravi6662" account claiming himself to be his cousin and that the original user of "ravi6662" had already go to USA. I already PM him twice the link to this thread, yet still no responses, yesterday i saw him online a while, and still he didn't even take a look into this thread.
