Not happy

I am super unhappy with vodacom, and cant even reach them to complain. Their new call centre service sucks, because there is no option to get hold of an agent, and when I tried to chat on their website, Tobi told me all the agents are busy I must rather send an email. For some reason my data advance is maxed out to R300 which I did not do, and it shows I loaded airtime yesterday and paid back R70 of the advance, which I also did not do, so what is happening? And now I cant even reach them to sort it out, and I cant load airtime on my phone! And this happens on a friday afternoon, so how long am I going to hava to wait before I can get this sorted out and load airtime!!???
