Bad service or no service at all!!

I sent a parcel to my sister in law from UK to South Africa.Just to notice this morning that it os coming back****ea not serviced by integrator.Apparently they ‘tried’ to deliver yesterday,but delivery should have been 24/4 already! You pay so much for a ‘decent’ courier and still end up having so much hassles.Now they are looking for a waybill number and the only numbers I have, are the shipment nr *** and the number underneath the barcode that was on the sticker app**** to the parcel E*** and then my customer number DHL*** and the consignment number which is the same as shipment nr.I have given my sister in law’s contact number as I am in the UK.Feel free to call me on +***.Shocking service!It is the first time I have tried DHL and not a good impression at all!
