MTN Service is DISGUSTING!

I entered into a top-up contract with MTN. The contrct was approved on Thursday (4-02-2016). I went into the store on Friday (5-02-2016) to fetch the phone. After waiting for approximately and hour an a half, I was told that the sim swap was completed and it will take 2-24 hours to be activated. I waited and waited the entire weekend and still could not use the phone as the sim card was still not activated. <br> <br> I went into the store again on Monday (8-02-2016) where I was told that there was a problem with the network on Friday and that the sim swap did not actually happen on the system. So they did the sim swap again and I was told that it would work by the evening. Once again, I waited and waited and the sim still does not work.<br> <br> I have been trying to get hold of the staff at the Fourways Mall branch but the phone is either engaged or they do not answer. When they do answer and I ask to speak to the consultant I had been dealing with, I am told that she is busy with a customer and that she will call me back (which she does not do). When she does answer the phone, she promises to speak to customer care and get back to me, but she doesn't.<br> <br> And I am still without a phone!!
