Worst customer service possible!

Been with MTN over 15 years, they cannot resolve the simplest of queries. Every consultant I speak to over the phone has 'issues' with their system, takes 30 minutes just to bring up details and then, I'll transfer you to billing, don't fall for that one, I think the people from billing fell of the edge of Earth, so if anyone ever gets through it would be a miracle. Do I send an email, takes 24 hours to reply, answer: both your numbers are receiving data, but I have 3 numbers. Did the third just dissappear, you are receiving payment. My query, not receiving data on my no, although paying for it? If any senior person from MTN reads please respond, #*** is my reference. If not I take it the rot starts from the top.
