No network for a weeks now since i made payments

I wrote a review few days ago. It has been a week of nothing but email after email. Twitter messages and inboxes. I even logged in a complain on your website. But guess what nothing fruitful. I'm not fuming because of your useless network but that because i paid a whole R475 for a network that's not even working. It has been a week since i made payments but no network. I don't want you guys to get to the bottom this because i know very well you won't. I just want my money back and thereafter you can deactivate this useless sim card of yours that has got no network. I want my money back. You guys are cruel. I wouldn't advise someone to use this pathetic network. I WANT MY MONEY BACK.!!
