30Gb data promo

I would like to query with regards to the # GB data promo. I took a MTN contract via green connect and was issued the number *** on the 05/04/2016 where I app**** or this contract on the 29/03/2016. The data of 30Gb as well as pro-rata data. However i was happy to join MTN family. the data which was loaded on the number was due to expire on the 14/04/2016 which I feel is fear as the promotion states that the data is for 30 days but I have had it for under a week. Please advice as to why I am not given my data bundle for the full 30 days. It looks like i was miss lead and not treated fear that because I took a contract with one of your on-billers I cannot enjoy the full benefits of being a MTN customer.
