Worst courier service in South Africa !!!!!

Dawn Wing Couriers must be the absolute worst courier service in South Africa, I have been calling for the past two days trying to locate a parcel that they are supposed to deliver. Every single time you get through to an operator they make like they are going to assist, ask you to hold and then kill the call, this has happened umpteen times in the last two days can anyone at Dawn Wing please get back to me with regards to parcel MK*** even if I need to come collect it. Rather than me trying to explain to my daughter why Father Christmas didn't bring her Christmas present!!!
