Vodacom Business: No service to have a VPN connect via their fibre services

Despite having received good service from Vodacom Business over the past month, our biggest gripe, getting my wife's laptop to connect to her corporate VPN, has been met with absolute not usable resolutions. My Service Request SR*** has been raised on the 15th of Aug 2021, with a 24-48 hour resolution turnaround SLA. Despite having spoken to several different consultants over this period (I called the support number nearly every morning), and having spent several hours on the phone, this issue remains unresolved to date. Numerous promises of callbacks by the consultants, including one this morning, never materialised. Escalating the matter to the Escalations team, 3.5 days ago, has also produced no results whatsoever. This has been an extremely frustrating exercise in how not to deal with a customer.
