Unhappy customer

Disgusting!!!!! First of all I send a parcel from Cape Town to JHB Midrand on Friday the 1st of November. Today it's still not delivered and lastly lying on the tracking system and saying there was an "attempted delivery" when my client didn't even get a call to notify her. So what exactly happens at the address???? Do you guys knock on the door and turn back the moment there's no answer? And I call this morning to ask about the parcel, I get reassured that it will be delivered today and again a few hours later I call again and get told it will be delivered tomorrow. This is the first time I'm experiencing this problem with Aramex and this is not acceptable.
