Very bad service

My parcel was supposed to be delivered latest last week Wednesday before 14:00, beause i will go on holiday Wednesday evening. When I phoned them after 15:00 I waited more then an hour for an agent to answer the phone. After my airtime of R150 ran out I phoned again. Same thing, hold the line till airtime ran out again. Phoned again, when I got hold of an agent she told me my parcel is out and it will be delivered before 17:00. The driver will call me. No call from the driver. After 17:00 I had to phone again, because I must go on holiday, but this time they were close. On Thursday they went to the wrong address and also after I told them I am leaving for holidays on Wednesday evening. Thursday I phoned again to arrange delivery for the next Monday morning, first thing. Everything was confirmed after staying on the line for 45 minutes again. Today (Monday) at 10:00 still nothing is delivered. I phoned again, again a new agent is answering, don't know what is happening. At least I was only waiting 20 minutes this time to speak to an agent. Bad news again. There is no record that they must deliver first thing today. She cant get hold of the driver but promise the parcel will be delivered today before 16:30. After the service I received since last week Wednesday it's hard to believe that it will be delivered. Sorry Skynet but your service is really very very bad.
