Misleading Sales Pitch

An agent S Govender contacted me on 13 March to offer me upgrades on my existing Vodacom lines. The amounts now showing on my statement is more than what we spoke about. I lodged a complaint and the feedback I got was that the agent was correct because he mentioned R149 plus VAS (the other contract was R99 plus VAS). What exactly is VAS? That is nowhere to be seen on my statement these are data contracts I don't need to have caller line identity and the like. I clearly recall him telling me: "for only R9 more you will be getting 5gb of data (I was paying R90 for 1gb previously). I therefore expected to be paying R99. Now if he said: "for only R9 plus VAS more than what you're currently paying...", then it's a different case. You are blatant *****! You are selling by dishonest means and the entire sales pitch is predicated on incorrect facts and misleading information. I wonder if Vodacom knows about this sly behavior by their so-called "trade partner"?
