Vodacom retentions disgusting

I recently wanted to cancel my contract with vodacom and go to telkom for a better deal...I called the cancellations dept and they promised to give me 5gig data and 175 airtime with no upgrade fee... for the same price at what telkom mobile was offering me at 299 per month for 24 months. Now 30 days later I find out that the data was only for 7days and im in a contract for 24 months!!!! This is disgusting service I'm so applaud by this if vodacom could not match the deal why offer make the offer they should have just let me cancel. I want my call recordings. If no resolution is found I am going to report this matter to ICASA and I will make sure it finds it way to a news paper im sure "Ask Wendy" will be more than interested to let people know never to be doped into false promises by retention based departments. These agents just care about their stats and do not care about the customers they service I'm sure she would have received a nice commission and now I'm stuck with the problems running around phoning all different departments trying to get what what was promised to me.
