Myworld Card Swiping 10 Times for Free One Gigabit of Data **** of Real???

I am having a ********** time trying to obtain the FREE Data that they promised customers for using their Myworld Card to Swiping 10 times in a Calendar Month for purchases. To date I am still battling to retrieve the May and June 2 GB Data from them. It appears to me that they have no control over the allocation of the Data to their Customers, which according to there customer service department are sourced from an external provider. I have spent hours with half a dozen of their Call Centre operators with no success or hope of ever getting my Data.
