Vodacom is a nightmare shem

If you want to have a heart attack, use the Vodacom app to pay your account. The whole of August I have been fighting VODACOM to allocate the amount paid using the app. I emailed my proof of payment almost everyday in August 2021, phoned them pleading with them to allocate the payment and they still have a nerve to tell me that I have not paid.... Njani when you have not done your job... And how is it that your own app does not allocate automatically???? What's the point of the app then???
