MTN itemised billing and gross incompetence

Absolute worst service provider I have ever had to deal with. Even though I am subscribed for itemised billing, and being charged for it, I never receive my itemised bill. Every month for the last 4 months, after receiving my invoice, I have to call the call center and request my itemised bill. Which then takes anything between 5 to 14 days of constant calls even though they say it will take 48 hours. The incompetence at their call centre is an absolute disgrace. And if I log into my account to download it, it says I am not subscribed for the service, even though I am, and I am being charged for it. It's a simple ****ing concept. You offer a service ( itemised billing), I accept it and pay for it. So just send me my ****ing bill every month. I do not understand why I have to struggle every month just to get you to keep your end of the service agreement.
