Unable to purchase promotional data

Please refer to my report dated 15 March 2016.<br> After being migrated to your new billing system I am unable to purchase promotional data (that lasts 7 days) - the *111# and *123# function does not work. The website and app does not have an option for PROMOTIONAL data. Vodacom's reply on my previous complaint was to contact me which they never did. I have contacted the call centre numerous times with no satisfaction. I cant call the call centre and be put on hold for 30 mins every time I need to purchase promotional data - your promotional data amounts to false advertising if I am made unable to utilize the service. Vodacom service is extremely disappointing and terrible and I have had bad after bad experience with you.
