Sad customer service tryin to activate my sim

We decide to call the call centre after doing a sim swap for our phone that was ******. we try making a call and a voice messages says that call has been re routed and that we should contact our service provider to activate the sim. we get to speak to sasekani from the call centre where she ask us security questions which we are able to answer and fail to answer one about our vodacom account number. we request her to ask us another question as that one we don't have, she informs us that we need to atleast get 3 questions correct. she had asked us already 4 questions before asking about the vodacom account. as the cell phone number that I had given to her belong to me with my understanding I had gotten 4 questions correct and only failed with one only which means I can proceed with what I want to do. she informs me that we cant proceed because am failing the security questions. we request to speak to the team leader which takes over 10 minutes to get hold of. Melvin magaogo gets on the line with us. the least that the he could have done first is to apologise for making me hold for long. he informs me that the system says we have failed that security questions and he cant assist.
