no one can give me feedback

I am a customer of vodacom for the last 4 years, I normally tell my customers that vodacom is the best, but for the last six months no one can tell me whom I need to talk to in clearing my name on their legal system<br> I cannot open new contract as this is always popping up, when I call I hold on and get the message \ ons herlei u oproep na die volgende beskikbare konsultant' but no one answers
