this guy make the order ,and we send the goods quickly at 10th,and after 17 days.the goods still on the road.but his tell us him want to cansel the order,but now the goods still on the road,after 8days .him receive the goods ,and him also tell us our goods not work and make the dispute .we believe our goods's quality, because we check it 2 time before we send it ,every funtion.until now we still believe this guy.so we tell this guy to take a video to send to our email ,but this guy tell us many many reason .but the result is that him cant send it.because the file too big,him need the partner the help him to do that ,and so on.later this guy ask us why him say to cancel the order.and we still send it ,now we know our goods is no problem.the problem is that after 17days him ask us why we send the goods .this is unbelieveable.
