Vodacom cannot activate sim

Purchased a new cell phone and contract from Vodacom online - order no Y***. New Iphone 5 and sim card delivered on Friday 5 June 2015. Sim was not active. Called activations department on Monday 8 June 2015 to have sim activated and was advised by Penelope, the consultant that Vodacom was having a problem with some sims and the number on my sim was different to that reflected on the Vodacom system. She assured me that this would be rectified in 24 hours as she would escalate the problem to a supervisor. 9 June 2015, sim still not active. I called the activations department again and after a lengthy wait for \the slow system"was told by the consultant that she could not activate my sim card and would escalate the problem to a supervisor. Since this is the only ineffectual cause of action Vodacom seem able to take to rectify the issue"
