Iphone 6s Plus 64 GB Gold

We are a vodacom business customer for a long time as our company with 14 cell phone contracts. I am working as business development manager for my company. I went to a vodacom store to do my upgrade in Canal Walk Shopping Mall in Cape Town at the first week of January 2016. My monthly bill is about R1100.00. Anyway, I wanted to get my upgrade done. My choice was a 64GB Iphone 6s Plus Gold or Silver. The consultant at the vodacom store told me that they have no stock. They told me that I can get it in a week time. After one week, I went back to same vodacom store but they again told me that they didnt receive the phone because vodacom head office didnt send the phone which was on the back order. Today is the 9th of Feb 2016 but I still couldnt get my phone. It is more than 1 month which I have been waiting for.. As business development manager of my company, I am strongly thinking to change all our company contracts with MTN at the moment because they are reliable and have cheaper deals!!
