Useless service

Having complained numerous times already about Vodacom's useless mobile data network, they still feel it is not important. They would rather send me an sms or have computer generated calls to confirm when they will be receiving payment. To pay for what on my data contract, when I have no data connection? They brag of a connection speed of up to 60 mb/s, but cannot even give me a steady b/s connection. The one call agent has the nerve to tell my girl, she can port if she wants. What is that? Useless, I tell you! I updated my contract in September 2019, and my old details is still on my invoices, so I presume it was also too much effort to change my details.
