MTN useless Service Provider

Call Ref: 1- ********** 3746 was logged on the 27th July with MTN Customer Care department. I requested Itemised billing sine January this year. I was assured I would received it within a week. the call was closed and I didn't receive my detailed billing. On eth 10 August I called in again to find out what is happening, only to be told that the call was closed in error. Same story again , receive the billing in a week. Call was closed again. And on the 20 August I called back to be told that MTN didn't have my correct email address. Noone could call e as they surely didnt have my cell no !! I spoke to Thembeka Ndlovu this morning who only made excuses and couldn't provide a solution to my problem. I am waiting for Manager Melani Laikram to call me.MTN sucks , I will be cancelling my contract and ensure that everyone I know will hear about MTN's pathetic service.
