Paying more than advertised - false advertising

I got a new contract on 31 January 2015 at the Telkom Mobile branch in Menlyn Park shopping center. The deal as advertised is the Smartplan 100 plan where you get a Samsung Galaxy S5 for R399.<br> <br> I just received my first invoice for the amount of R702.19.<br> <br> I understand paying the initial wifi activation fee of R200.00 but I don't understand now paying R502.19 for a deal that is advertised as R399.<br> <br> I am unhappy about this since I also asked the consultant what the price of the deal is and he confirmed R399.<br> <br> No additional costs were communicated.<br> <br> Account number: ***<br> Service number: ***<br> Invoice number: ***<br> Invoice date: 1 Feb 2015<br>
