DE ACTIVATED MY EXISTING CONTRACT

In February 2015 I recevied a call from Mondore marketing agent for Vodacom with promotion for WIFI router with databundle contract. I accepted the offer and WIFI router with sim card with delivered to me on 04 March 2015. I called the *** number to have the sim card activated. I took me 3 weeks to get through to an consultant. Whom said the line will be activated in 8 hours. Never happend. I had family emergeny in mid March 2015. I eventualll went to Vodashop, In Menlyn. And by error the consultant just did a sim swap on my existing line as if it was an upgrade*** which i. I was unable to follow up and when I started calling them again and not only did the consultant deactivate the sim card for *** but the new line iswas never activated. I had to purchase new sim cards for both these devices. I contacted Vodacom on Facebook In May 2015 but only got promises from we escalating the matter to senior consultant and emails but nothing was ever really done. I will get a call to apologies for the inconvenience suffered but nothing still done. I am now at point of that I wish i can return all devices and cancel my contract ***. But legally I cannot
