unusable data bundles

This is a follow up on a complaint I lodged last month, every time I buy airtime I get data bundles that can only be used after mid night. I do nt need these bundles as they keep me thinking I have data when I really dont. I currently have over 300mb that I will not use. I have run out of airtime and real data bundles because I kept thinking I had enough. Please I do not want these free data as it is deceptional and confusing. It makes it difficult to monitor ones real data bundles and eats into airtime
