Appalling service

We were contacted in January 2016 by Keith (Rewards Call- ***) who offered us an upgrade on a contract we have with vodacom for wi-Fi. The deal sounded good being a carry over of data &a reduction in the amount we were paying -effective immediately.<br> On the 1st/2nd of March we contacted vodacom as our data was forfeited &we wanted to cancel the deal..They directed us to\Trade Partner\" (***4) who directed us to rewards call -(Sharn)-who directed us to Mondo Mobile -***/ ***.<br> We've spoken to amongst others Bianca, Tristan, Kristen to get a recording of the conversation had when the deal was made. All promised to get back to us and after several calls TO DATE WE HAVE RECEIVED NOTHING. <br> They have however informed me that we cannot cancel the contract as we had 14 days cooling off period. THE OLD CONTRACT WAS EXPIRING IN APRIL..The NEW ONE COULD ONLY BE EFFECTIVE April (legally)....But we had 14 days in which to cancel. .How's this possible.....(But \"KEITH' promised that it was effective the time he made the deal with me.)<br> Please advise...what course of action can I take. I'm no longer interested in this upgrade anymore due to their poor service "
