They won't do sim swap because of their *****

<p>I took out contract last year September with Vodacom and they activated 2 numbers in my contract of which I don't know the second no as I never used it, so now that no keeps on accumulating arrears and I called them to resolve the issue they always say they are investigating since last year,I now want a sim swap because my phone was ****** they say they can't do it because my account is on arrears but my actual number is up to date only their ********** one is. I am being inconvenienced as I d's not activate that no and client care won't help me and it's not my fault they made a mistake. Cell no inn question is ********** 954</p>
