Disappointing service

I ordered something and I have been tracking the status of my package and since the the 10th it has been saying it was onboard in a delivery vehicle from Durban to Port Shepstone. Today is the 12th and when I called in the morning I was assured delivery will take place today, later on another consultant tells me no it will only be delivered on Monday. I call again and I am told it should have been delivered today and soon trying to call the driver they are unable to get hold of him. I was then told they will notify the supervisor who will call me regarding this matter, but I did not get any call back from them. I am very disappointed in the level of professionalism I am receiving from this company. The original order is from Labels4school and all they have been saying as well is that delivery is going to take place today.
