Unable to check PC data balances on my R219h router

I have sent a message to vodacom asking why I cannot check my PC router balances. I can log into the router login page but then when I want to check my balances on the PC then then it jumps around from my balances login page to some other vodacom page. Can someone contact me on *** asap so we can sort this thing out please because the call centre cannot help me. All they can say is to take the card out my router and put it in my cell phone. First of all it is a total nuisance doing it that way and secondly I used to be able to get my router balances on my PC until it all changed. WHY?
