What you say is contradictionary to what @Evil E. says. who of you is right? a week via dhl or 30 minutes.
A week for a tracking event to give a result? If a parcel is processed at a sorting facility it will show in DHL website within an hour at most times (lets say a few hours to be on the safe side).
I work at DHL although with domestic road transport in Sweden but our systems works pretty much the same way as DHL Express system does when it comes to tracking shipments.
