No minutes allocated for August

On the 17th of every month I receive an SMS from Mtn telling me that I have been credited with a certain number of minutes, SMS's and Data. This month (August) I didn't receive that notification and the number of minutes I have didn't increase on the 17th. I sent an enquiry to "Customer Care". They rep**** that I was provisioned on the 17th. I rep**** that I hadn't been provisioned - that was the very reason for my enquiry. They sent the same reply with screen shots and said that I have been provisioned. Again I rep**** that I haven't. This is very simple... log into my minutes on your side, see what I had as a total on the 16th. Then see what my minutes were on the 18th. You'll very soon see I WASN'T provisioned my minutes. Could someone who has the ability to make a decision please look into this? Replying that I have been provisioned and then ignoring my email really isn't professional at all.
