Vodacom refuse to stop *****ing and won't answer queries

Vodacom registered me for a vodafone live something and are charging me R4.95 a day for whatever this is. I have asked for what exactly it is they registered me for but they can't answer me. I have asked for proof that I requested this registration but they can't answer me. They can't show what or why I am registered for this thing yet refuse to reverse the charge on my bill. Are you having such financial problems that you need to ***** R127 from a customer? Fix your system and start answering your customers instead of ignoring them.
