DHL dropped off wrong package to client

I am employed by a big Embassy and DHL were supposed to collect a parcel from us to deliver to a client in the Congo, not only did DHL not deliver the parcel, or even pick up the parcel. But they decided to deliver the client another woman's parcel. <br> <br> Client is currently sitting in Brazzaville and DHL is sitting on their backsides refusing to collect the parcel from us as they decide what to do with themselves. <br> <br> They have already collected the incorrect passport from the client, but he is now stranded. Get off your backsides and do your job.
