False Advertising

Cell C are the worst company to deal with. They advertised a deal on their website. When I enquired about the deal they said it was a mistake.After a week the deal was changed however when enquired about the deal they advised that the pricing is not the right one. Please can cell c employ competent people as no one knows whats on the website as for the call Centre what a *********** and rude bunch of people. Why advertise the wrong pricing not once but twice.
