Bad service

I have order two items from takealot on Wednesday 16th of December. I then received an sms stating that the delivery will occur on Saturday morning 19 Dec before 7am. I then waited, but nothing was delivered. At 09:00 I called their customer service and the lady said that it was a system error, the delivery will never take place before 7 am but the message should have read that delivery will take place before 7pm. I was then promised that my parcel will be delivered during the course of the morning - around 10:00. At 13:00 nothing was yet delivered. I phoned again, and I requested that the delivery must please take place before 15:00 as I would be leaving at 15:00. By 15:00, nothing was delivered. I phoned again, when I was informed that my parcel have not left the branch yet. The supervisor then phoned be back - Amir (he was very helpful and professional) and we arranged for a delivery at 17:00 at an alternative address. Meantime, someone from the Menlyn branch phones me at 15:30 and tells me that the delivery man is now at the first address, even though I told them that I left at 15:00? Eventually I received my parcel at 17:30, and then the one item I ordered was wrong!
