False Advert

I did a upgrade on my contract with Vodacom on the 03/03/2015. <br> The special that I took is advertised as follow: <br> <br> Alcatel One Touch Idol Alpha <br> Was R229 Now R129<br> <br> uChoose Flexi 150<br> Includes R150 Airtime , 500 MB Data ( Anytime) , 500MB Night Owl. <br> <br> So I went to Vodacom . I took the deal. I received my phone and all is well. <br> After a couple of days I found out , when visiting the shop , that the 500MB data is not included!!!!<br> Your add clearly state that it does. I have the add with me . The salesperson NEVER told me its not , the day I took the phone. Is this how you get people to take out contracts with false adds, and lies?? <br> <br> I want my data as promised every month , for the 24 month contract. This a a total **** from such a big company.
