Telkom mobile prepaid simcard locked for no reason!!

I am disgusted with the Telkom device. I am a prepaid customer and it is twice now that my simcard is locked. This is frustrating as I had active bundles on both simcards. Now it's all a waste of money. When I try to make a call I get a message saying "your account has been locked, please contact customer care". How am I supposed to do that when I can't even dial out? I even tried to use the online chat service and the agent then picks up that "Rica is not done" that's why it's been suspended. This is ridiculous because I've been using the simcard for the past year and had Rica'd it on the day that I bought it.
