WRONG SIM CARD WITH MY NEW COTRACT

i just received my new phone but with the wrng sim card, my new phone uses a micro sim card and they gave me a normal one. I went to the Vodacom shop in Centurion where they told me they cant do anything about this except pay another R70 for a simswop or wait another 7days to get my new simcard if i call this number ***.<br> <br> This is absolute nonsens as i need to get this phone and contract activated, if this problem occurs i will cancel this application and contract and i will go to another service provider.
