Falls advertising and misleading customers

I just want to explain what happened to me at Vodacom in Canal Walk(mega store?) I app**** for a tablet contract on 15.12.2017 - got approved and ...... looked on the system and said there is stock and she is ordering it on the same day - it will take 3-4 working days I have been calling e ery day since and I drove from Mamesbury to Canal Walk for none of my calls gets returned, neither any communication from Vodacom On the 4.1.2018 I was adciswd that there is no stock and it is discontinued but again I was promissed a call to discuss same package with replacement product but still nothing Imaam abbas is ignoring my calls, not following up after I was assured there was stock, absolutely no communication I expect what I aigned for or a better product cor the same price ... I cannot afford a more expensive contract and I feel it is falls adcertising and misleading customers Vodacom should keep up there word and honour my sigend contract
