Struggling to complete a sim swop

I visited Vodacoms' store in Blairgowrie Plaza to do a sim swop for my daughter. The sim swop is for her Cell number ***. I have visited the store at least five times and phoned in a few times as well. First we had a sim that received the Vodacom signal but was blocked to any other call or message activity. Then they changed for another Sim card that does not register a Vodacom connection signal at all. The consultants are called Kush and Danielle. They have tried to help but I think this transaction is out of their depth. Their shop number is ***. I do not think they have escalated this quick enough to the manager of their store, who perhaps would escalate to someone in Vodacom who has the power to cut the \Red tape that Vodacom keeps tripping over"and help this customer have her phone and number work again. One and half weeks and a sim swop not working is not acceptable. Please can someone at Vodacom sort this out!"""
