Online Add not honoured

I went onto the Cell C website this morning as I was interested in a contract and came across a deal on their website for a Samsung S6. I clicked on the \get it"link and entered my details. <br> Only for a sales consultant to call me back and tell me to go and look at the website now - the deal has changed. Honour your adds Cell C !!! You spend millions on advertising only for it to be a lie."""
