Sim swap problem

Today I upgraded my contract for the number my wife uses ***), although I use the mobile device (number ***). Both contracts are on my name. I had to do a sim swap to a nano sim card. I paid R63 for the new card. Arriving at home I found that the card was swapped for my wife's number and not for mine. I phoned the call center to explain the unfortunate situation and was told that the sim swap was permanent and cannot be reversed. <br> <br> The only solution I am offered is to go to a shop and buy two new sim cards so that Vodacom can swap back my wife's card to a mini-sim, and my mini-sim to a nano-sim. Is this really the only solution for this error which will cost me an extra R126 (R63 + R63). <br> <br> I trust that you will be able to solve this issue for me without me having to pay R126.<br> <br> Kind regards,<br> Jannie
