Shocking service and poor communication

My contract is coming up for its upgrade and I had Cell C call me on the 30th October which is coming up to 2 weeks now. I agree to upgrade to a iPhone 6 and also being promised that my phone will be delivered to my house that Monday the 2nd Nov which was one of the main reason for the upgrade. Monday came and I had arranged to make sure someone was available at the house for the delivery. I decided to call Cell C. After waiting on hold for just over 20 minutes! I was helped (Sort of). After another 10 minutes I was told that the phone had not even been sent out and will only be sent the next day. Already now frustrated I arranged for a person to be at the house again. Tuesday, Wednesday passed and on Thursday I called again. Again, another 20 minutes later I was answered. Now not only was my phone not sent but now they tell me they do not have any stock available and are waiting on stock! After telling them I would like to cancel and was told it will take 48 hours! Then i was told that the phone will arrive on that coming Monday the 9th so I agreed and I waited till Monday. Still nothing! I called today(10th)and I was told again that there is still no stock! This is just SHOCKING!
