Afrihost mobile data doesn't work.

This is the 4th consecutive day I have called Afrihost to try and get my mobile data, which I have already paid for upfront, to work. I have had to buy MTN data in the mean time. Afrihost are incapable of fixing my mobile data. They just refer it to their critical care department who refer the issue to MTN. MTN says they can't find anything wrong. So now what. Don't buy Afrihost mobile data it just stops working and nobody knows how to fix it.
