Is the strike still on?

I have two numbers with MTN - my own through Altech, where I have received good service and my son's directly with MTN which has been a constant headache. The current problem is that his data has not come through this month and I have called several times into the call centre several times and they keep promising to sort it out but nothing happens. Latest ref *** on cell number ***. The same thing happened last month but then at least they loaded the data the day I complained. It is ***** to charge for something that is not supp****! Then secondly I have been trying for months to get a refund for extra data that was loaded but I did not request this. One cannot get to speak to anyone who seems to really know what they are talking about and I am extremely frustrated. Please can someone sort this out??
