I was informed that i would receive the package within 48 hours, which i did. I was given 5 days upon receiving to cancel the contract. I phoned the next day and proceeded to cancel the contract before it was activated. The agent said it was fine and the courier who had brought the package would collect it which they did. But my contract had been activated since 25 august 2015 for an amount of R109 each month for a sim and device which i returned and dont have. </span><br style="color: #9b9b9d; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; font-size: 12px; line-height: 17. ********** 05249px; background-color: #ffffff;" /><span style="color: #9b9b9d; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; font-size: 12px; line-height: 17. ********** 05249px; background-color: #ffffff;">I tried to cancel the contract as i was told that i have seven days.i called the vodacom cancellations line ********** and was told to contact \The Rewards Group"directly on ********** 00 or ********** 666 the landline number.
