No delivery no response

I order a 5gig for R99 pm telephonically I was told it must go to the back office for approval and to see if i qualify then 1 week later my account is debited with the R99, now 2 weeks later numerous email no device received i was told sales would call me this has not happened, you try calling them they transfer you from one department to another and eventually the call is dropped, now half way through the month I am paying for something i will not even use?
