Agent gave me wrong information - Vodacom sort this out

Hi, on the 26th of April a Vodacom sales agent phoned me and advised, based on my usage patterns, I should migrate from a Smart M package to a Flexi 350 Top Up package. She assured me that for the same amount of money, I would be able to allocate the amount of data and voice minutes for each month. I then phoned the call centre on the 30th of April to ask for more details, and the person tells me that I only have R350 airtime, and that if I want data, I would have to pay extra for that. Please go and listen to the voice recording of this conversation, I was told (sold) something completely different. The reference number is *** I am very unhappy with the service !!
