Mtn billing

I called MTN to complain about them charging me for the use of airtime whilst I do not have courage. I called the call centre multiple times using 173 & 1555. So by the end of the 3rd day they told me I had reached the quota for the number of times I can call without reaching a solution to them taking my airtime. They promised to call me back but that was all lip service.<br> <br> Today what they did is that they consumed my airtime although I had a data bundle. Now I do not have airtime but have data bundles even though I was on the net. This has been going on for a while. I am sick of calling into MTN because the consultants treat you like you are the one *****ing from them.<br> <br> I have had enough. Thank you for the worst service.
