Vodacom Deal

I was recently browsing the Vodacom online store and came across a deal that looked like a black Friday deal. I contacted Vodacom and the sales agent advised that I should take a screen shot and send this to the admin department and that they would have to honour the deal. I attached the screen shot for reference. Vodacom called back to say that the price that was advertised online could not be detected and that this was the price of the contract and did not include the device but all the other deals are also advertised like that and includes the device. Vodacom did not even apologise nor thank me for the mistake they made on the website. My intention was to upgrade but now I will see my 2 months out and end my 2 contracts. Loyal customers are just not appreciated.
