Failing to get our contract activated

I app**** for a contract at MTN Jabulane Mall on the 21/11/2015. I received an SMS confirming that my application was approved. I went to collect the phoned on the 28/11/2015. I was told that the manager that needs to authorize for 2 phones is not in on that day. I went back to the store on the 01/12/2015 I was told that the system is offline. The lady took both phones and put them on top of my contract to ensure no one touches the phones. They then told me that I can get someone to collect the phones for me as long as I write the letter accompanying the person. I did so and sent my partner to collect the phones on the 03/11/2015, and he was told that the person who work on the Carlton system has left for the day. I then went to the shop again on the 05/12/2015 and I was told the Samsung Galaxy S6 Edge + was sold. The service on that shop is very bad. The manager can't speak to client and often very rude and has got a very bad attitude. I have always had good service from MTN and have always worked well with the company, hence I'm taking 2 phones on contract now. I don't think I'll be doing any business with MTN anymore after receiving such terrible service.
