Pathetic service from DSV Mounties

A week ago I upgraded my cellphone contract with MTN. Last week Thursday the parcel was with DSV to deliver. On Friday they said the parcel will be delivered on Monday. Monday came and no parcel was delivered. On Tuesday I phoned again and the parcel could not be delivered but I was not contacted even once. So the parcel will be delivered on Wednesday between 10am and 1pm. At 12am I started phoning DSV Mounties. I phoned a total of 4 times and every time they try to call the driver but he did not pick up once. DSV even said they will get back to me with an answer but they never do. How does MTN choose a courier company that can not deliver a product like they are suppose to. Not one attempt was made by the driver to deliver the package and I am not allowed to pick it up at the warehouse. Can you please sort out your stuff so that I can get my package that I paid for.
