Bad service

On the 15th of January I went to Autopage branch in Vanderbijlpark where I requested to add another contract to my existing account 9(I thought this was the best way forward as I've never experience problems before) the whole process was started with all the relevant documentation in place(I was then still with MTN and I started the process because my contract expired with them) I wanted to keep my current cell phone number because I use it for work. After two weeks and no help at all by the Branch Manager I decided to go to the Vereeniging office in the hope that I will be assisted in a better manner. Rudy the consultant was very quick in uploading all my details and agreement was made that I will change from MTN to Vodacom and still keep my cell number this was done on the 31/01/2015(the port request was submitted) and now it is close to two weeks later and still I cannot make use of this contract because the sim is not active. What is making me more furious is that I will be billed by MTN and Autopage which I cannot afford with the package I took with Autopage and I have to hear it over and over that it is at the Head office. How can I go cancel this contract????
