Seller said he has other problems? Like selling a faulty handphone to someone else. Of course people will complain. He is just ignorant thinking to only sell off the faulty phone and think it will just go away. He is also selling something on behalf of a friend (not sure if it's real) and not want to take responsibility for it. It is already stated in the rules and regulations here that you want to sell or buy something on behalf of friend or family, it is your responsibility. No blaming on others. From this, it shows this seller is naive and irresponsible.
