Still No Assistance and No Feedback

I have requested help from Vodacom concerning the INSTANT TOP UP Value added service for Top Up Customers which is not functioning / Activated on my number, since the 19th of April 2019. Client services 135 insists that it is Activated and working, i am requested to dial *136*04*amount# i have tried doing that and it constantly replies an error message "Your Account is Not Provisioned For Instant Top Up" when i go onto the My Vodacom App to buy airtime there is no option to "Add to Bill" only Credit Card, The Terms and Conditions state that Top Up and open Contracts have this service available on request. https://www.vodacom.co.za/vodacom/terms/instant-top-up-terms-and-conditions yet Vodacom Insists that the Value added Service is Active. The Issue has been reported and since today have not had any feedback on what is going on, no one has even tried calling for the past 3 days, calling into the customer Service dept. I am just told no feedback, the last feedback i had was a lady that called days ago telling me that she will make sure my issue receives priority, she was supposed to contact me again, but to no avail, agents get annoyed when i phone in and start querying, please is anyone available to assist ?
