Cannot buy from Vodacom app

I've just checked, I've got 3 business contracts expiring in December 2017. None of them will be renewed if this isn't resolved immediately. I included a screen shot of the app message in my original review.

Dear Lucian Sans-Souci, I received your SMS, but it makes no sense to say that my number is not listed as a Master Account Holder. 1: I am the official company proxy for Vodacom matters and multiple proxy letters have been issued to Vodacom over the years. 2: I have personally handled all upgrades for the company for the last 10 years. 3: I am able to purchase data/minutes/SMS bundles galore, via USSD *111# menu. This last point is the most valid. If my number is not listed as a Master Account Holder, why am I permitted to make purchases against my post paid company bill via USSD, but not via the app? And, I used to be able to use the app to purchase data etc, only the "new style" app has prevented me from doing so, and in particular, now that the 2x data bundle offer is only available via the app. You need to lift what ever restriction there is on my number without further delay. You will see that I have given notice to cancel my number already, and the 2 other business accounts have not yet been upgraded, pending the outcome of this.
