Hi all, thanks for the prompt replied . Really appreciate it..

The platform usually updated as "sent" it mean they have already sent it ... I been using that platform for quite a period of time , very trustable platform...  As I mentioned , I occur the same scenarios before, and keep asking their support before , all they did is replied me , saying the system of their confirm sent it already .. And after usually 2-3hour , it then appeared in blockchain.info .. But today is the worse , didn't see it until now ... I haven get the TX information, as their incharge already knock off.. Gmt time 2.39am now .
(Their platform didn't suspend withdrawal, and I double checked , it's status as "sent" )
