False advertising

I have recently bought my 12 year old son a Vodacom Smart Kicka phone and as per the store Vodacom offers 100MB for 6 months and according to the store the data will be automatically loaded by Vodacom, 2 days went by and nothing, so I called Voda and they said I must sms “New” to 31118 and it will be activated,that was done and still no data, went back to the store again and they gave me a long story...now can someone please sort this out?? His number came with the new phone it is ‭+27 ********** 48‬ but I prefer if you contact me instead of him ( ********** 375)
