Pathetic service from Mobile Talk

I bought a mobile router which I struggled to receive because it was sent to the wrong address, then I received sms confirmations that the router will be delivered on the set date but that never happened. After numerous emails sent to their customer care the router was finally delivered, I received it last week Wednesday and to this day it's still not working. I used my R84 airtime and my 1G data calling and sending emails, I asked one of the call centre agents to call me back but she said she won't be able to call me even after I told her how much I spent on airtime to get their issue sorted. The ladies name is Tamara Short. Please get this issue sorted, I know my account with be debited come end of the month yet the service was very poor. I also need my airtime and data refunded and urgently
