Vodacom online please fix my order

I upgraded late November to 2 cellphones that comes with 2 sim cards, 800mb data and free smses. Only one number is working, i have been calling with no luck in getting assistance, i went to the store and i was told the second sim is not registered under my name therefore they cannot assist. Vodacom, i am paying for 2 phones, 2 sim cards and their smses as well as data. You are robbing me as you are not delivering fully. Can you please fix my second sim and allocate my data and smses from date of upgrade to both sim cards.
