Vodacom failing to do sim swap for contract line

I lost my phone and the past couple of days I have been struggling to get Vodacom do a sim swap for my contract line. 1. I have been to a Vodacom shop in Kimberley for more than 4 times and they keep telling me that they are getting a system error. They have logged more than 3 calls and still no luck. 2. I have called the customer care centre more than 5 times and they also have logged calls with the back office and they keep advising me to go back to a vodacom shop so that my case can be escalated. 3. For one of the logged calls I received an sms saying query had been closed. Yet still my case has not been resolved. 4. So it seems we keep going in circles. This has been happening since Sunday and its now Thursday still nothing. Thats almost a week.

I don't understand why my case cannot be resolved and I dont know what else to do now. This is very frustrating and disappointing. I have never missed any payment for my contract.
