No help from call centre for over 5 days

I recently got ****** and my phone amongst other things taken from me, I reported it as ****** and asked for the sim card to be blacklisted, I went and got a new sim card with the old number and two weeks later the call centre blocked my new sim card, When i call the cell c 140 line, it tells me my sim card has not been rica'd and i am unable to connect to the internet, I am using an old blackberry and have activated BIS.<br> <br> I have since asked JEt Edgards Helpline people to make sure the sim card I have is not the one that's blocked and to cancel whatever contract they have on my number which i didn't sign for in the first place, I have been waiting since last friday 10th July 2015, i called in 3 times and each time I have been advised a Network team would call me to resolve my network problems and cancel the contract, they told me their S.L.A was 48 hours and I have waited way longer than that. It's frustrating to not be able to check one's email on the go and I am losing business because of this.
