Second attempt: Prepaid data bundles "disappearing" (i.e. being ******)

**Trying again because the first time I posted this, Vodacom didn't get through to me. ** After using prepaid data bundles for years, in a period of two weeks about a week ago, along with the new USSD menus and revised data bundle offers (that quadrupled prices overnight) my large Vodacom prepaid data bundles (2 gigs) have totally disappeared, twice. It also happened to another Vodacom number in my family in the same area as the same time. I get a zero balance reading but where we are, because of poor reception, it is literally impossible to use that volume of mobile data at the rate Vodacom is suggesting I have done, so I know it's not me. I have no content subscriptions. I've been with Vodacom for years and been using prepaid mobile data bundles for years. I know my consumption, my devices and the network in this area well. If this is not resolved promptly, I will switch. It's that simple. I won't be ****** from this way; it's enough that their mobile rates are so ridiculously high already although that I blame on poor regulation. With fibre and 5g on the move, though, the MSPs better sort their stories out fast...
