VODACOM IGNORING ME FOR MONTHS WHILST BEING OVERCHARGED EVERY MONTH

I have been trying to get an answer from Vodacom for months now about a R50 handset charge on my account even though I never received any handset. I have heard all kinds of excuses, but not one legitimate answer. They are ignoring my emails at customer services now, I have not heard back from the last Hello-Peter complaint I made. I don't know what else to do. This is really weird and quite disgusting. PLEASE GIVE ME AN ANSWER VODACOM!!!!!!!
