Prepaid Data Add On Plans

hi everyone,

does anybody know whether or not Vodafone has gotten rid of both the Favourites and the Socialise prepaid data add on packs??

all I can find is the option to purchase the $5 internet essentials pack, however I do not want to buy that one as I want to be able to purchase a data add on, using my preexisting credit.

thanks for all help received!
