Vodacom refusing to confirm if payment was received

This is my 3rd email regarding the service of Vodacom employees in a month. Past 2 posts were regarding my lines being suspended and today it is about customer service. I received an sms on Saturday indicating that I need to pay my Vodacom account although my Vodacom debit order is scheduled to go off tonight on 29 March 2019. So, my wife made the payment and sent the proof of payment to an email address given to her by accounts department. 6 days later and NO response from Vodacom whether payment was received. This morning my wife called Vodacom accounts and asked "was payment received" and the accounts consultant refused to assist her saying I should phone in and she will tell me yes or no. This is ridiculous as my wife handles everything and she is always assisted by a Vodacom consultant!!! There is nothing difficult about saying yes payment received or no payment not received as she was the one who made the payment so she has the right to know whether HER money was received or not!!! Vodacom customer service is non-existent! Some consultants are never willing to assist or go the extra mile. I am really disappointed in Vodacom as they use to be the best network but they have gone downhill and I am definitely not upgrading any contracts again. Work on your customer service!!!!!!!!
