gdex usually like this one, i bought my sis s7e in lazada and the seller posted with GDEX, gotta to say, its one of the slowest and unresponsive courier there is...

Item posted 28th Dec, check online still with the status 'Outbound to hub', called em few times and no answer, finally on 31th Dec, i personally go down to their office and asked status for my parcel, and walla, its already there since 29th Dec yet no delivery done..

Poslaju way better
