moved to prepaid now no data!!!!!

I moved one of my Vodacom contracts to prepaid. I was told on the 29th May 2015 to turn off the phone for 6 hours and then load air time and data.<br> I did this and also loaded a 1 gig data bundle and a 250 meg data bundle and R55 airtime.<br> Now the phone cannot connect to the internet or keeps saying no data.<br> I went to a vodacom shop who said I need to do a sim swop, which I did and still no data. I can only make and receive voice calls.Vodacom is also still charging me for a 500 meg data bundle which was attached to the contract even though I had cancelled everything. All I wanted was to keep the number and move to prepaid.<br> If this is not fixed up tomorrow, 1st May I will move all my other vodacom contracts to another network.<br> Mr De Combes<br>
