Sim swap problem

I took out a new contract on an existing prepaid number on 23/12/15. I received the new phone and sim on 24/12/15. I immediately called the activation's dept to activate the new sim. They informed me that it would take up to 24hrs to work. <br> <br> The old prepaid sim was successfully converted to contract, but by the 26/12/15 the new sim was still not working. I called customer care and they advised me to go into a Vodacom shop in order to RICA my sim. I did this, but was told in the store that the sim was already RICA registered. <br> <br> I called several times afterwards to customer care and the activation's department, but no one was able to assist. I eventually called the retention's department in order to cancel the contract and they advised me to try the sim swap on a new sim and still nothing. I am still waiting on them to get back to me as to why it has not been successfully activated.<br> <br> It has now been 11 days and 3 sim cards later since taking out the new contract and yet no one is able to assist me in doing a successful sim swap in order to use the new phone.<br> <br> This is extremely bad service from Vodacom and I can't believe that they cannot do a simple sim swap.
