Lodged a complained and was promised feedback

I had a problem with MTN, still do, and after several attempts to have it resolved, I turned to ICASA for help on 7/11/15. I received an e-mail that I would soon be contacted. I have not received proper feedback yet, although it is way pass the turn around time initially mentioned by ICASA. I spoke to Magdeline twice and each time said she would follow up with MTN. I believe they are the problem but it's been tow months and still NO answer. In the mean time they have billed me 3 times for this service already...which was actually ONE query!
