5 days and still no help

I went to Vodacom Westgate on the 24/11/2015 to order my cell phone for my Upgrade that I was due for on the 1/12/2015. I have not been able to get hold of WIlson for 5 days. They still do not have any stock. Johan the Manager said he would source me the phone and call me back...its been 2 days and I'm still waiting for my call back. the Admin Lady NEVER knows anything. she doesn't know who is supposed to work when. she has no clue what time employees are to start. she doesn't offer to take messages and nor does she ask if she can help or if she can pass me on to someone else that could possibly help me. what good is a Receptionist/Admin lady that knows nothing about the shop or helps with ANYTHING. im actually so upset with VODACOM Westgate Repair Centre.
