BAD sim swop - failure!!!!!!

Good day<br> <br> I'm a VERY VERY VERY upset customer. I upgraded my contract on 1st July 2015. Today is 2nd July 2015 and I STILL don't have ANY network on my phone.<br> I went to the shop at Kolonnade centre for a second time and they did try to help me. They were very helpfull. The guy told me to swicht my phone off and leave it off for at least 1 hour, then turn it on and check the network. Then if no network, I needed to switch it off again and take the battery and sim card out for 5 minutes. And repeat this process a few times.<br> 7 hours has past, since I was at the shop today (2nd July 2015) AND STILL NO NETWORK!!!!!<br> When will I have network? For 2 days I've been disconnected from the world. I'm paying for my new contract, but I can't use it. I don't have contact with any of my friends or family. This is unacceptable and I'm getting impatient.<br> I sincerely hope someone can fix this ISSUE now!!!<br> PS. You won't be able to phone me, since I don't have damn network!!!!!!
