One huge headache

I am furious...... I have had problems before but this is the last straw. I received a new SIM and rooter as I upgraded. It's been more than a week and the sim still not active. After numerous emails messages etc......they now say that the problem is with Telkom and the sim is active on their side......like huh.?? I have reset and even tried to set up the rooter ... But still nothing. How can the sim be active if it won't even work in a phone and it doesn't even show on my portal?? You tell them you're loosing money daily because you can't work and all they say is sorry. Also when I upgraded.....I had to accept via email......but nothing happened only to find previous package has been cancelled yet no new rooter.....or sim. I asked the sales consultant what will happen to my roll over data I paid for......and no response only to find out.....once the service is cancelled, you loose it. This is my last resort because I don't get anything done with them.
