Vodacom seriously devious and pathetic service

There should be an option for ZERO stars. Had a billing query since January, if that's even possible. Was lenient enough month after month whilst they spun me utter bull**** and deviously made me enter into a contract. I have been charged incorrectly since January and made contact again on 31 March to which the only feedback I receive is that they will provide me with feedback when they have it. I dont feel this is right and I would like to make contact with an Ombudsman to discuss the multiple times Vodacom has ****** my money and left it unresolved. They dont deserve to be in business especially in these tough economic times.
