Bad service from vodacom online

During March I did a upgrade on my existing contract and after perusing Vodacom online initially I found a suitable contract they advertised flexi 120 contract (Sony Xperia L1 & PS4 bundle). I verified that there was available stock and subsequently placed my order on the 19 March 2018 Receiving no feedback I called to verify and they told me the stock is on a back order but the on the 19 March 2018 when I spoke to the consultant she told there is stock available on this deal and till today if I phone they say the stock is on back order I am a customer for many years with vodacom but I am starting to lose respect for vodacom. Now it started making sense as if Vodacom was playing for time. It's bad service and false advertising trying to play for time on items.
