VODACOM CANT PROCESS A SIM SWOP

I am a very disappointed Vodacom customer as I cannot seem to get a simple SIM swap processed. I am on a premium Vodacom Red contract with a linked data share SIM to my main contract line. My Data sharing SIM line got lost and I have already visited a Menlyn Vodacom outlet twice but they always some problem in terms of processing a simple sim swap. I understand that Vodacom has processes to prevent ***** when processing sim swaps but why must this be such an issue that affects me in providing for a service that I am paying for, more so I am I am not processing the swap telephonically but am going in person with full identification on me. I do not intend on going back to wait in a queue to be served only to be turned away as I am very very busy person and expect Vodacom to give me the value of my moneys worth through reliable customer service delivery.
