Vodacom poor service and false info

Consultant phooned for updgrade on data contract. The info of data and contract that was loaded was complete different information. . Clearly false information was given by consultant. 1- It was clearly stated that I will receive 60KB day time data as customers don’t use night data. This is not the case according to this contract and only 20KB was loaded. 2- I clearly state what my full balance is with Vodacom on both contracts. Consultant then gave premium that will be less. This is now not the case when i received the contract and false advice was given by consultant. Email was sent to costumer care and complaints to void the contract but no response.
