False Advertising

You probably have this all the time, but customer service at vodacom just gets worst by the day! Our family being customers of Vodacom for more than 20 years, so today we want to upgrade and do the online thing as we got an sms stating there is an upgrade. Did the whole thing, phone the call centre and we are set. The package is a 2 for 1 for R649 per month! Get confirmation sms stating that we have to pay R1077. 89 monthly subscription! Now how in Gods name do you advertise a deal for R649 and then tell me I have to pay R1077. 89??????? How the hell does this work???? Please do get an agent to phone me so that I can cancel all 5 contracts! And then not to mention the rudeness of the call centre agent I spoke to! Terrible!!!!
