Upgrade of Contract Epic Fail - very bad service

I was due for an upgrade on 28/03/2016. <br> <br> 29/03/2016<br> I went to the store and upgraded my contract from a Smart L to a Smart XL, received a Samsung S7 device and requested a sim swop for the new device. The after 18 hours of waiting for the new sim to be activated, I phoned the store and was advise that the sim swop was never activated.<br> <br> 01/04/2016<br> The new contract was supposed to be implemented as of today. When I checked my status, I was still on the Smart L instead of the XL. After phoning the store, I was told that the upgrade was miraculously cancelled by the system. In other words, I walked out of a vodacom shop with a phone worth R13000 and it was not even captured correctly. Now, I was given two options:<br> <br> 1. To let the upgrade take effect on 02/04/2016 - with this I will be liable for the payment of BOTH contracts - Smart L and Smart XL for the month.<br> 2. To let the upgrade take effect on 01/05/2016 and forfeit the added benefits of the new contact as well as pay the more expensive package of the two (which strangely is the Smart L).<br> <br> I do not want either of these options. I want the Smart XL effective today or I want to cancel my contract immediately.
