Iphone 4Gs

I have ordered the IPhone 4Gs 8Gb on the internet, as I have 2 other contracts with Vodacom , I decided to get a third one , <br> the contract was all good and well accepted and I received a confirmation email to state that they will deliver the phone .<br> the next day I get a call from the call center advising me that there is no stock as it is a discontinued model and they can give me the IPhone at almost triple the price. I declined as I wanted to spend no more than R200.00.<br> the crux of the matter is not that there is no stock , but the fact that they keep on advertising the phone on the internet for the same price . is this a sales tactic to advertise a discontinued model and then upgrade a person to a more expensive model?<br> and to add insult to injury I went to president hyper shopping center and saw the exact same model advertised at chats cellular for the same , price I went into the store to enquire if they have stock and was advised that they do have and will have on for me by Monday the 22/06/2015, they will call me once its there.<br> I am still waiting for their call !!if they removed the phone from the internet and if the lady said no stock I would have left It
