The most horrible experience with MTN

It has been weeks trying to just get my MTN itemised billing and tax invoice for February from MTN. I contacted them numerous of times. I was transferred from one consultant to the other because they were not loaded on a certain system. I spoke to about 8 consultants who couldn’t help me . I dropped the call eventually. I called a week later and a request was logged to date I still have not received my billing documents for the month of February. I called in again I was told it was emailed to me. I did not receive that email another request was logged . I still do not have my billing documents. I have lost hope.
