Vodacom sales horrible experience

Good day,

I received a phone call from this number *** and a lady who identified herself as Nokwanda tried to sell me a promotion, when I declined she asked why and I told her relative to the competition- the prices are still steep. And she continued with her agrressive tone and asked me what competitors are offering and I told her that is she is selling a product then surely she would know the competition landscape which she then raised her voice and said that Vodacom is still cheaper and that why would I not want to take the offer because it is a great offer and they are doing me a favor with this offering because they can see how much data and airtime I am using.

I explain to her that I have uncapped WIFI at home and then she went on to say then why do I buy data and I said because I travel...at this moment I realize how hostile this phone call is and I have already declined yet she is being rude and trying her best to almost scold me like a child for not taking up this amazing offer that Vodacom has for me. When I confronted her about her tone she hung up on me...I then called Vodacom customer centre and they said they have no record of the lady however the number she used to call is an external company that does promotions so they cannot really help me and apologized. I explained to the nice lady from customer care that Vodacom should look in into this because the lady did say she is calling from Vodacom so I hold vodacom liable because they made my information available, and that this has left such a bad taste in my mouth that I am going to port to another service provider.

Literally it took this one phone call for me to consider this, I am really unhappy with Vodacom because they could only apologize for the experience I had, I asked the lady to maybe look at the company that uses that number because they identify themselves as Vodacom and we will hold Vodacom liable.
