MTN poor service

<p>Called MTN call centre Tuesday morning just after 7 on Tuesday 18/04. I asked for one of my lines to be typed up with a once off one gig data bundle. They said it will take 2-24 hours to reflect. I kept on calling and no one could tell me what the problem is... They just said that it is loaded on my account but not on my side yet.... It is now Thursday and still I didn't get it. So I have been billed for something I didn't get.</p>
