Incorrect Sim Swop

I did two upgrades at Vodaworld yesterday and they did the simswop on the wrong number. I only realised this late in the afternoon when getting back to Centurion and went down to the mall to the Vodacom shop to try get it resolved and was told by Lebo that I can pay them again for the new sim. I said that is crazy as I have already paid a few hours ago and it was done wrong. She then called another girl with a green tshirt who told me that i need to go back to Vodaworld to sort it out, they cannot help me and that this is the 3rd person that they have done this to today. You work for a company and advertise that they have made this mistake so many times on one day to a client that is already worked up and now sitting without a working phone as my daughter does not live with me and had the new sim but not for her number? I was told they work independently and do not form part of Vodacom. Needless to say I was really mad as I would never have made it back to Midrand from Cent in time, so spent all night with no working phone.
