Shambolic Vodacom customer 'support'

There is absolutely no execution of any customer service aspiration.

I receive a Statement for a number of accounts linked to it, but never any invoices. In the past one could email a customer service office; now one is directed to use a Whatsapp channel, which merely provides a Menu (that does not include help for Invoices); when selecting to engage with a 'Support Specialist' (what a misnomer!), they are always unavailable. How difficult can it be to help customers!
