Data expiring early - lost 1.7G

I recently complained on this forun on how my MTN data miraculaously expired in week instead of the transacting period of 2 weeks. This was the R89 for 1G fortinight. I am really frustarted to say that noone had listened to me or even tried to resolve my problem.<br> I then bought another fortinight 1G for R89, and to my surprise the dat also expire dafter 7 days instead of 14 days. I am hurt because altogether i lost 1.7G of data because of this MTN problem, over and above that MTN automatically startr billing me out of bundle rates because little did i know that the data had expored. Is there anyone who can give me a lasting solution to this. <br> What I only did as the custopmer is to switch off the phone and stop buying the data again. Thsi is not a sustainable solution, Is there anyone from MTN to honestly help me find a lasting solution.
