Vodacom failed to service a customer yet again

I moved and phoned the Vodacom call centre to update my address about a month ago Agent told me it'll only show on my new invoice Get the invoice this month Old address reflecting I continually just get bad service with Vodacom agents and it's happened so many times I don't even know why I'm surprised anymore Please for the love of bunny rabbits can the company setup something on the app where we can update personal details?
