Pathetic Service - Vodacom

Prepaid with Vodacom is a nightmare. The deductions made from the prepaid amounts diminish faster and faster and on a daily basis. Further: The coverage in the Mount West area in KZN is way below poor. Its pathetic. Calls are dropped in EVERY conversation, incoming or outgoing, which, to say the absolute least, is frustrating. What is also frustrating is, Vodacom don't have a 'complaints' email address. Considering the pathetic coverage and call dropping, how is one to avoid going through Hellopeter to get service?
