MTN Late Delivery

On Monday I requested an cellphone upgrade online. Thinking it would be faster, I called the MTN store closest to me as well. The lady on the other end said I could upgrade but that they do no have that phone in stock but that she would call around to look for one. So she did, and called me back to say there is one at another MTN store 30 minutes away. So I left work early and sat in traffic and finally arrived at the store. The one store had no idea what I was talking about when I asked for the name the lady had given me and directed me to the 2nd store. They also had no idea what I was talking about. Then I got another call, the lady apologized - she had given me the wrong store and I had driven there for nothing. I was told it would be couriered to their branch in 3 days. its day 4, and nothing has happened. Then I get a call from the online application saying my phone (the one from JHB) will be couriered to me within 3 days and that the courier company would contact me shortly. Because of the lady's mistake they marked the package as urgent. It is day 3 - no call and no sign of the courier. Please find out where my cellphone is, as it should have been delivered by now.
