MTN doesn't take thier customers serious

Hi I lodged a complaint to Mtn stating that I have a problem with thier night express data that I bought to submit my tender documents. And which till update they haven't answered me or give any necessary feedback.and I even Lodged in thier enquiry page but I the people who are assisting me are clueless of what I'm talking about or the is no communication in thier offices. I have voice recording of the conversations we had with the consultant and I have screenshots of what I'm talking about. Cause I even asked the last consultant which happens to be the shift manager at that time to give me an email address were I can send her pictures of what I'm talking about. which she gave me the complaint department email address. I'm really hurt and heartbroken for what had happened to me as a person who survive but tenders I lost my life cause of thier Data.
