That's an interesting question. I have kena many cases already, some ask 101 questions, say will deposit $$$ today, then later say not free, forgot lah, this lah, that lah, then just disappeared. Some one minute say wanna buy, next minute change his mind. If not, say wanna COD but date and time confirm later but when the time comes, failed to contact me. It's a waste of my time replying to such people.
