Overcharging

On the 6th March 2014 I took out a contract for a Mini Ipad with data. That Contract expired on the 6th March 2016.Being the 24 months that I signed up for. <br> However, as usual Vodacom think that thy can carry the contract through to the end of March 2016.<br> When I took out the contract I paid a pro rata rate from the 6th March - 31 march 2014. So when the contract ended on the 6th march 2016, I should only have been charged a pro rata rate from the 1st -6th March 2016.<br> I did not take out a contract for 24 months and 25 days.<br> You can charge me for the R75 data for the full month of March, but you cannot charge me for the Apple Ipad for the extra 25 days. This is theft.<br> I want a refund for the overcharge of R 129.05 ( R160.02 less 6days R30.97) ***-1
