MTN's inept, useless customer service

I have been trying to get my itemised billing for the day after the cutoff date of my last bill. It's now over 3 weeks. I have phoned customer service repeatedly. The responses thus far have been: wait 3 days; wait 3-5 days; we will escalate your query; wait 3 days for the escalation; wait 3-5 days for the escalation; we have sent it to you but the delivery status of the email was incorrect; wait 3 days for the delivery status to be updated; we understand your frustration etc. What a useless company!
